Net Programming

I am trying to write a protocol for distributed computer nets. It is going to be a layer between an application and the net to make programming easier, similar to RMI or CORBA.

What desirable characteristics you think it needs to implement, /prog/riders?

If you are using a high level language that supports it, proxy objects that represent an object on a foreign machine, where method calls get forwarded across the network and the return value gets sent back transparently.  For extra credit, send exceptions back and re-throw them.  Something to look at might be how objective-c does distributed objects (method signatures are extended so you can pass my copy or by proxy), though its probably simpler always pass method args by copy.
