No, sorry, a "page" (HTML + images) is considered extremely heavy if it
has more than about 75K in it. 14.4Kbits/sec = 1.8kbytes/sec, which over
slip probably results in 1.5K/sec at best. 1 meg takes 11 minutes at
this rate.

Compression isn't that widespread yet, and the most that has ever claimed
to accomplish is a 3x speedup.

Not all compressions are created equal :) For most applications I don't
think this is significant compared to the baud rate - as long as the
application could decompress more than 1.8K of compressed text per
second it shouldn't matter.
Sending compressed VRML over a modem using compression *may* result in
a performance decrease, but that's more a quality of implementation issue
for the modem - this is true for other compressed media as well (mpeg,
jpeg's, etc).
