Erm, at the risk of getting flamed, where does IAX come into this 
picture?
If I re-implement IAX(2) in a different language (not using iaxcomm 
except as
a refererence or test )
and want to sell a product based on it can I do that, or do I need a 
license ?

(I come from a BSD background, so the implications GPL still confuse me)
