If I were them, I'd think long and hard about such a product, and in the 
end probably not do it. Its the only realistic way to do G.723.1, but 
the market for that is not so big. For the much larger number wanting 
G.729, the main CPUs keep getting faster. There are 6 core Xeons now, 
and there are supposed to be 8 cores by the end of 2009. You can have 4 
of those in a 1U chassis. Their speed is just going to keep running 
ahead of a card.

The only real DSP that needs to be offloaded is EC, because a large 
number of channels of that is probably going to challenge the main CPUs 
for some time to come.
