SetPoint with BT works very well for me. Although at this time it is using the built-in Microsoft stack. The only problem I have is every time I open my CD-ROM tray (and/or close it) the Bluetooth icon reappears.
Another concern I have is I have to choose my hardware around what will work well/at all with my KVM. I am currently using a wired mouse and keyboard because of how heavily I use my KVM, and I don't want to have performance hits. I don't care so much about programmable buttons or features, as I don't really game and I wouldn't be into that too much.
I know you had a thread about looking for a KVM a bit back - do you have any issues with this mouse or anything else when switching? Alternatively, is Bluetooth better than RF/Fast RF?
I would really love to go wireless, just can't deal with stuff not working.
