This is what I plan to shoot for, but the basic communication between
client and server will be well defined, and open, packets. I will build
classes that will automatically encode themselves into these packets,
and decode the packets into themselves, but there is nothing to stop
someone from writing their own...

This will be pretty nasty for sure. Every mobile object will have a
version integer, and I'll be able to check with that. However, I hope
to have a better, more automatic system in place.... Haven't thought
about it too much yet..but auto-downloading .class files is not out of
the question.. Probably could work some magic with the ClassLoader or
something...

Looks like both ADSL and the cable folks won't be here for a while. The
telco says call back in a month..the cable guy said check back 3Q98.
Musta moved to the wrong block :P
