Mumble fits pretty much all of your requirements there, even though it might not be what you're looking for. The only disadvantage I see it having is no offline messaging, but there are other solutions you can use for that.
I also got an invite - I specified "Other" (Arch Linux) - which is pretty surprising.
Pretty sure they invited the vast majority of people - I only saw one out of about 10+ people without an invite so far.

This happens very very rarely. The only time you can really hose your system without reading the news is by using --force (don't).
Uh. TF2? Valve will soon port all of their titles over too (e.g. DotA2, CS:GO, etc).
If they're not AAA, what is?
