AFAIK, asterisk 1.6 can do sending and receiving faxes, but no direct 
T.38 gateway. That would leave your process like this:

Fax Machine A--> FXS port on digium card --> receive T.30 fax on asterisk 1.6, store and forward as T.38 fax --> Sip with 
t.38 --> internet --> Sip with t.38 --> receive T.38 fax on asterisk 1.6, store and forward as T.30 fax --> FXS port --> 
Fax Machine B

Counting that everything works well on the IP portion of the 
communication, you might have something, but the "store and forward" 
process that has to be made twice to emulate a T.38 gateway on both 
asterisks would make it a very slow process to send a single fax, having 
that faxing is traditionally slow. So, it's pretty much a little more 
elaborate answer of "unlikely to be pleasant".  A direct T.38 gateway 
for asterisk would be awesome in any case of use.
