Have you seen SCOP:
http://www.srcf.ucam.org/~dmi1000/scop/

It has bindings for Scheme, C, C++, and Java.  The Scheme bindings are
courtesy of Sven Hartrumpf:

It seems to be for Chicken & Bigloo, but the code looks pretty compact and
straightforward - porting to PLT should be trivial.

I'm not sure if you'd find it any better than XML-RPC for your purposes - in
fact the core data format seems related to XML-RPC - but it does have the
benefit of already existing.  It could make sense as a transport protocol
which could be used to carry sexps, if you're looking for something
semantically richer than what SCOP itself offers.

That's what I do, over HTTP.  But then, I'm doing that in web apps, so it
does make a certain amount of sense...  :)
