I've run across some discussion about train use... It sounds like a
moving train is about the worst case scenario for ricochet. Cells are
small and handoff doesn't sound very robust, so you're transfers drop
into 9600 territory. One comment I saw suggested that remote ssh or
telnet sessions were impossible on a moving train because of the small
packet size and latency. Waiting for a train or plane was great.

I forgot to mention, advertised bandwidth is 128k down, 64k up with the
USB connection. Serial is rated lower.
