I'm running a mud on test basis over a 28.8 slip, and have had no 
problems with speed. (CSLIP that is...).  I've even run other 
applications as well as having X running (and I've only got 8megs of 
ram), and the mudders have not complained about lag at all.  I've only 
had like 10-15 ppl, but even then have the performance been ok.  I guess 
the major drawback is that the modem is analog, thus errors occur and line 
can drop without much line-noise.
