Hotkeynet can make this work for you without taping down keys. You would have two keyboards running on 2 computers, and HKN would be able to make each keyboard control any of the WoW's with different behavior if required. So for example

Pressing F1 on keyboard 1 could send <F1> to WoW1, CTRL F1 to Wow2, F1 to Wow3

Pressing F1 on keyboard 2 could send SHIFT F1 to WoW1, Shift F1 to WoW2, F1 to wow3

Doesnt matter which PCs WoW1,WoW2 and WoW3 are on
