[AG-TECH] Echoing and choppy audio on Mac to Mac

[Gurcharan S. Khanna]

chris,

i wonder if it could be spec'd out in terms of full-time work. it's so 
annoying and would
be so beneficial i feel like committing resources to getting it done but 
i need some definite
parameters to be successful. how many hours do you think it would take 
to complete? and
if it's already started by someone, would a different effort be redundant?
