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

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?")
