Somebody must have read this thread, I just watched 2 Avocet Cyclades TS-100 units that have been listed for past few weeks -- quickly sold an hour after last posting in thread. :-) There is also a 4-port Lantronix unit (for less than $3) that uses Intel's ipx420 processor and 32 MB memory. Would work for multiple computers or one computer BBS with 4 serial ports.
