It is indeed nontrivial. Actually, it's better described as "a pain in
the arse". I've already done it, though, so you don't have to if you
don't want to.

Using Pluto (or other serialization library) to implement message
passing in a multi-lua_State implementation of parallelism is
downright trivial. Performance isn't everything it could be (there are
potential speed advantages to be realized from doing the serialization
and deserialization in parallel, rather than serially) but depending
on one's exact requirements it might well be sufficient.
