Ah yes, different port numbers.  OK, a separate "otalkd" makes sense.
Here's a hack-ish suggestion:  Pretend that the "otalkd" protocol was
supposed to be big-endian only (as in network byte order), and provide
a replacement "talk" client for your little-endian machines.

This would nicely accomodate the a large number of sites with lots of
SunOS and Solaris boxes that want to use "otalk-BE" protocol.  If you
can make otalkd somehow discover that it is talking to an "otalk-LE"
client, that would be nice, but I'd be happy with just "otalk-BE."
