Has anyone had any experience with using an Object-Oriented Programming
Language in a distributed processor environment?

We are currently developing a product in which there may be up to 36
processors, all of which are peers; objects on all processors are part
of the same object universe.  When we began a couple of years ago, there
was no OOPL support for anything like this, so we "rolled our own" using
C.  We wrote a router that shuttles messages and replies between objects
(regardless of the processor), and a database that coordinates
transactions over multiple processors.

Since then, we've been trying to keep abreast of developments in this
area.  In particular, we would like to be able to use a real OOPL
so that we would have better support of inheritance (as it stands,
classes are supported only administratively.)  The mainstream languages
still assume that your application will be compiled as a program on one
processor, but I'm hoping to get pointers to language extensions or
special techniques that allow us to extend this.
