I believe he said the outgoing stream was two 128k ISDN lines, which
from my ISDN memory I remember as actually having a 112k throughput (the
other channel being used for signalling, etc). Since you can only push
packets out one at a time with a single tcp connection (i think) 128 is
definately not going to make it out, even if the one possible listener
could receive data that fast.
So a lower bitrate is most certainly necessary. 24kbps is a good one to
choose if you're interested in modem listeners. A lot of people like
56k but I don't think they realize that most people with 56k modems get
more like 40k throughput or so. I think going higher than 100k is
