Personally, if you’re doing game networking, I say don’t bother. For many things, it’s a time-saving abstraction, but it IS low performance, which means you won’t be able to use it in most games - so even if you start using it, you eventually have to do all the work of coding something better sooner or later anyway.
It’s a good starting point if you want to do lots of remote method calling (um, funny that, given the name), although again performance can be an issue - but it’s a lot better than your own attempt would be for the first 5 or 6 versions :).
Several people here have used it successfully for game situations where perfroamcen didn’t matter, and typically where it was less hassle to do remote method invocation than to write a protocol, and handlers, and … and … etc.
