No fixation.  Just that IMAP is the best protocol for remote mail 
reading and pine is already available and supporting IMAP.  And
as a bonus it supports MIME.  This *is* something that BBS'ers dont
already have..  multi-media mail.

You dont need encrypted TCP/IP!  A good mail reader supporting MIME
could handle encryption packages automatically!  MIME also supports
many other things that "they do not already have".

I dont think its easier.  I think something like SLIMAP (serial line
imap) would be the easist thing to implement.  IMAP runs over a network
stream and there is no reason it couldnt run over a serial line stream.
The code written for imapd already runs on stdin/stdout...  It wouldnt
be hard to port to run on a serial line connection.

I dont think offering IP to the masses is the right solution right
now.  Its not appropriate for the BBS world.  Getting people to use
remote mail clients is something that the masses could take to
alot easier.  I think this would be the prefered way to read mail
since the user interface could be made more friendly,  sorta
the 'prodigy thang'.  I dont think it matters what protocol is used
in the end but I think its something that should happen, and something
that we as cypherpunks have an interest in seeing happen.
