How many hardware vendors support g722.1 ? g722.2 ? How pleasent are
they to the CPU? How much does it cost them?

I think polycom does and both are very heavy on CPU.

Naturally I don't suggest to use speex/wb where there is enough bandwidth
for g722 . But right now AFAIK g722 and speex are just about the only
two free alternaitves. Non-free means loads of licensing issues ("I
swapped a network adapter, why can't I use g729 anymore?")

You can use wideband speex with the googletalk client on FreeSWITCH to call into a conference also running on FreeSWITCH and conference in wideband. Its very heavy on CPU for speex you might get 10 channels on a beefy box at most.
