Take a look at Termite for Gambit Scheme; its focus is different from yours, but it seems to be very good at serializing stuff (including continuations) and automatically proxying the rest (e.g. file descriptors). (I don't think this is actually a good idea - intra-datacenter traffic is much faster, upgrading becomes hard in this scheme, and your security model needs to be quite complicated - but I'd be interested in learning what you find.)
