That is very cool!!!

Yes.  It's not a big difference.  I was thinking of seeing what could
be done easily by pretending to be B2F and just not supporting the
attachments.   Now I don't have to try that.

It's a good enhancement..

I'm just describing Airmail - not making a suggestion for JNOS.   When
JNOS gets B2F it'll be time to put the "server" functionality of
Airmail on the shelf and relegate it (Airmail) to the easy packet
client mode.

Sure.  Raw bandwidth remains the same but it can be used differently.
Simply send a message with B1 BBS forwarding and then send it again
with TCP - both on 1200 baud.  The difference is vast.  (And no - I
doubt the B2F will give any gain..  Which is why we should look at
creating B3G (ha ha) to use a modern compression scheme and gain
another 30% or 40%.)
