spandsp doesn't try to reimplement all of HylaFAX. It reimplements only 
one piece - the T.4/T.30 code. I have a half implemented "spandsp as 
class 1 fax modem" which I put aside. People are using spandsp happily 
for things like fax to e-mail. Introducing HylaFAX would really slow 
things down. That said, I'd really like to complete the class 1 modem 
interface, and make HylaFAX an option for people.
