A way to key map to game pads like the Logitech G13 and gaming mice?

An in-game voice chat system?

I saw something in a twitter feed its was for keyboard and mice only at this point.

I think you might be able to use one of them fancy new mice like Razor Naga and bind those extra buttons to do things. If they work I might get one it could really help in PvP, if they work.
