I think your problems are more to do with the nature of your modems
than any inherent problems with medium speed SLIP links.  I lived for
two years quite happily with a LADS circuit supporting a full time
point-to-point SLIP connection running at 19.2kb.  No fancy modems,
just a pair of local data sets.  19.2kb SLIP is subjectively quite
reasonable, and I found that even on a heavily loaded line supporting
NNTP, a couple of telnet/rlogin sessions, regular SMTP traffic and the
occasional FTP, the delay wasn't all THAT bad.

All bets are off when you start talking about pseudo-full-duplex modems
like Telebit Trailblazers or MNP6, or noisy lines or lossy serial interfaces.
But let's identify *these* as potential areas of problems, and not tar
the underlying technology unjustly.
