I've seenover 600 posts in here about problems with keyboard/video/mouse (KVM) switches. While I agree that a Logitech KVM would be ideal, here's an alternate idea that might be simpler to support and implement.
Instead of using an actual KVM, I recommend that we look at using multiple unifying receivers.
To do this we have to address a few issues:
a - users will need to switch their video themselves
b - users will need to switch their audio themselves
c - the unifying receivers must be addressable (maybe up to 4 addresses?)
Let's talk about video first. While a KVM would let you switch video, most monitors now have multiple inputs. There are also LOTs of video switches with IR remotes. In my case, I run all my video (and audio) thorugh my home theatre AV receiver. What I'm saying is that there are alternatives to using a KVM to switch video, and this solution I'm proposing assumes that you are okay with using one of those solutions instead of a traditional KVM. Is it perfect? No. But I'd be okay with pressing a hotkey to swap my keyboard/mouse and button on a remote to switch video. Of course, you could use a KVM to swap just your video and use the solution I describe below to swap your keyboard/mouse. You moight even be able to get the same hotkey to switch everything at once.
Audio falls into the same situation as video here. Lots of alternatives and easy to solve.
Now for the Keyboard/Mouse part.
I don't know what the limitations of the current unifying receivers are, but I think Logitech could use some clever software to make this work with the existing receivers.
What we need is at least 2 unifying receivers that can be uniquely idnetified and can operate in the same room without interfering with each other.
If that's possible and Logitech updates Setpooint to support this, then we could do this:
1. Plug in the first receiver.
2. Set the address (via Setpoint on the PC) to A.
3. Pair my mouse and keyboard with reciever A.
4. Tell Setpoint on the first PC that I want to share the mouse and keyboard with other PCs.
5. Plug in a second receiver on a different PC.
6. Set the address (via Setpoint on the PC) to B.
7. Pair my mouse and keyboard with receiver B.
8. Tell Setpoint on the second PC that I want to share the mouse and keyboard with other PCs.
9. Now set a unique hotkey for Receiver A and another hotkey for Receiver B.
10. When I press the hotkey for Receiver A, Receiver A becomes active while Receiver B ignores all comms except its hotkey.
11. When I press the hotkey for Receiver B, Receiver B becomes active while Receiver A ignores all comms except its hotkey.
12. I can extend this to up to 4 unifying receivers.
While not a true KVM solution, this simple solution could allow many people to switch all the peripherals that use the unifying receiver between 2 or more PCs. I believe this would drive people to buy more Logitech peripherals.
In my case, I run my audio and video through my AV receiver, so all I need is a way to swap my keyboard/mouse between my primary and my alternate PCs. I already have a K800 keyboard and I would gladly replace my MS mouse with a Logitech mouse if it meant I could switch between PCs in this way.
What do you think?

Thank you for this interesting post. I will be sure to forward it to the appropriate product team.
If your PC's are Bluetooth equipped, the Logitech Wireless Solar Keyboard K760 announced today may suit your need. It can pair with up to 3 devices via Bluetooth and quickly switch between them. Please watch this space, as we will be posting a support video on this keyboard in the upcoming weeks.

What would be interesting is something like synergy with milti unifying receivers. Synergy is a tool for keyboard mouse sharing across multiple systems and their monitors.
With synergy as you roll to the edge of you mapped screen edge, it picks up the mouse/keyboard on the next system.
Having a design where synergy is driving the capture of the mouse / keyboard across the set of recievers and "turning on" the correct system based on crossing from screen edge to screen edge would be very powerful.

I had successfully been using KVM switches with patented USB DDM (Dynamic Devices Mapping) technology for sharing multi-receiver of Logitech UnifyingReceiver keyboard and mouse since last summber (2011).
Recently, I got the newest firmware of the USB DDM KVM switch. And now, I even can combine multi Unifying Receiver into
just one and plug in to the console of the USB DDM KVM switch. How cool it is , in my case, I had been able to pair 4 logitech wireless keyboard and mouse by using just one Unifying Receiver with the USB DDM KVM switch (my is 4-port DDM KVM).
The SetPoint (for PC) and Control Center (for Mac) are both working without any problem when connected to the USB DDM KVM switches I tested. I had been tested with Windows 7 64-bit, Windows 7 32-bit, XP, Win Vista, Mac OSX and even with iPad (for keyboard only).
It is not only working but switching with no keyboard/ mouse latency :-)

Had that problem once, endlessly replacement of dongle from one PC to the other. Then I got a program from Microsoft Garage called "Mouse without border". Now the mouse just follows me on both PC's It works over the local network.
