Well the standard KVM you need wired KVM. But I am looking for a KVM that supports USB wireless Keyboard and Mouse.
I need it for my future Mac and old P4 XP computer (I might switch to Windows 7 or Vista later).
So here is the complete list

MUST:
1. support wireless connection for K and M
2. support Mac, XP and Ubuntu
3. price is moderate.....

Additional feature support:
1. W7, and Vista (both 32bits and 64bits)
2. support third channel to TV
3. additional audio (third channel to TV)

I hope someone can help me out with this...

Thanks a lot guys. I have been really busy with college stuff. Got frustrated with my new schedule ....
