[more stuff on using xml snipped]
this is exactly the scheme I am planning, right down to the telnet proxy
server. In-server message passing (as, indeeed, the whole database) will be
represented by structures that map directly to and from a flavor of xml, so if
Fup tells Martha "I love you", this will be internally represented by a
"someone_says_something" object and externally represented by xml looking
like
<someone-says-something sayer='Fup'>I love you</someone-says-something>
one issue here is how rich one should make the messages, as there is obviously
quite a bit of extra bandwidth here (parttally an artifact of my example). One
could compress the messages, but that's some extra cpu time. Another issue is
how you filter messages inside the server so a text-based client doesn't get
sent messages that only make sense for graphical clients. Both of these should
be pretty easy to make efficient.
If the internal-external distinction and machinery is hidden away somewhere,
and its operation made totally transparent, one could then build a system on
something like pvm (<url: <A HREF="http://www.epm.ornl.gov/pvm">http://www.epm.ornl.gov/pvm</A>>) and PIOUS
(<url: <A HREF="http://www.mathcs.emory.edu/Research/Pious.html">http://www.mathcs.emory.edu/Research/Pious.html</A>) to split a bigass mud
across multiple machines. Attaching a remote object such as the crab's brain
process would then be a piece of cake.
