Big +1 on this. Making it a community project would seriously help their
Linux users and as a result their reputation (Skype's) would increase.

I'd also be wary of removing Alsa support completely. Perhaps just
accessing alsa in a way that doesn't break the pulse alsa plugin would
be a good start, then they can work on adding a libflashsupport type

The problem that Skype has that Flash doesn't is support for multiple
devices so their extension plugin may have to be slightly cleverer in
that respect (although the pulse plugin would just have to have a
different stream name for ringing and call and you can leave it up to
pulse config to configure differetn devices etc.)
