I'm using a G7 wireless mouse on a notebook with 802.11g wireless network connection (which also uses 2.4 GHz spectrum), I noticed that the mouse would update position changes slowly when I had very high traffic on the wireless network, like when I was transferring files to a file server.
In addition, the mouse would lock up several times a day, requiring me to unplug the usb receiver and reconnect it to reset.
I am a licensed radio technician, without going to the trouble of actually measuring the power output of the G7 transmitter, I suspect that it is quite low in comparison to 802.11g. The 2.4 GHz spectrum is rather congested where this mouse is used, I myself have 2 802.11g wireless access points, and I am in range of at least 6 others.
I would very much have appreciated if this design used blutooth, or a less congested radio spectrum. I believe that there are usable frequencies in the 700Mhz, 900MHz and 1.8 GHz bands. I would certainly appreciate if future designs had more options than 2.4 GHz available.
Radio Frequency (RF) power transmission follows the inverse square law, meaning in short that power drops off dramatically with distance between the antennas. So...
In order to boost the signal between the G7 mouse and the USB receiver, I found a short USB extension cable and stuck the USB receiver under the table directly under the mouse using velcro tape. Reliability has been improved using this technique to the point where I am not cussing at the mouse several times a day now.

This isn't really an answer to your suggestion, but I would like to state that I have observed the wireless mouse-lag issue for years and that my fix is to set my router (a Linksys WRT-54G, in this case) to channel 2, rather than the defaulted channel 6. Even with a laptop doing a file transfer to another computer on my local network via Wifi, there's no stuttering or lag.
