I've considered picking it up, but after a discussion with a friend of mine, we decided it probably wasn't worth it unless it went dirt cheap.
There's not going to be enough situations where we have the free time to play, enough people with decent PCs to play, and copies of the game for each one, and headsets/mics on top of that, and so on and so on.
It's neat, but it's not ideal and it doesn't replace a real life tabletop.
