CORBA can be compared with COM, SOAP and XMLRPC.
In fact the OReily book on XMLRPC does a very 
good job of this.  Also you can find more here:

http://xmlrpc-c.sourceforge.net/xmlrpc-howto/xmlrpc-howto.html

XMLRPC is to CORBA as machineForth is to C++.  
You can understand XMLRPC in about an hour.  
(I don't know how long it takes to understand 
CORBA, but I still don't get it and I've even 
written a CORBA IDL parser in Oberon).  SOAP 
is the "ANSI Forth" of this group.  As one of 
the XMLRPC gurus puts it:

"Basically, if you like XML-RPC, but wish 
the protocol had more features, check out SOAP."

Good: They give you a flexible way to deal
with other peoples problems.

Bad: Possible create a false sense of security?
(Hey, I've caught all of the exceptions in this
code, so it must be bug free right?)

Sounds like a fun project.  And it's important to
see projects like this done too.  Yes okad II is
impressive, but people can always say "well of
course Chuck can do something interesting with
it".  And while I am impressed with much of the
code other hobbyists have submitted, it would
be nice to have another example of something
someone got PAID to do.

Keep us informed of how it's going.  I imagine
you'll use UDP for the communication?  (Since
that's already working)  What kind of things
are you controlling?  Perhaps as a "community"
we can help get this thing off the ground?

Hey, I'd forgotten about that site!  Great that it
now has an emulator.  I'll check it out.
