I must echo what John said, with a few additions.

I too have Pac Bell's ISDN (2 bearer channels == 112 kbps). However, I and
my ISP coordinated this whole thing, so we have Combinet Everyware 2060
"SOHO" boxen which, when using the default Combinet Proprietary Protocol
(CPP) instead of SLIP or PPP, does up to 4x compression on the data. While
we haven't tested the throughput yet (it's only been a week), I have enough
bandwidth to simultaneously see seven video streams and the occasional

Because of a latency problem I've uncovered two hops upstream the audio is
choppy, but I'm working with my ISP's ISP to fix that.

I can heartily recommend the Combinet boxen. The only thing they don't
have is a bank of LEDs that show the thruput (like VU meters on my stereo).
