League Friends App for PC (with optional voice chat?)

Example, I've got a laptop that while it may not be the most powerful (or have enough storage to download the whole game), would be neat to talk to friends currently on League.

I don't know, just thought it'd be nice to have. (Then maybe add voice chat to it... I don't know. I know Riot doesn't really like voice chat IN the game/client, but having one that could easily connect us to those we're in a game with and is completely optional could be pretty sweet. I'd buy it.)

Okay, you got me. I'm just asking for more Riot apps...
