I'm considering the inclusion of rpyc, with appropriate changes (possibly lots). And would like to know your opinions towards this.
Might think about reviving the ILU kernel (just the runtime, not the stubbers) as a Python-only module. Open source, pretty complete bindings to Python, multithreaded, threadsafe, etc., etc. On the other hand, I haven't even compiled it in 6 years :-). The key advantage would be that ILU speaks a number of different RPC protocols under the covers, and it's straightforward to add new ones. I'd love to see our implementation of wmux (a way of multiplexing multiple virtual connections, in either direction, over a single TCP connection) actually in use.
