I know that routing (aka transport layer) is outside of the domain of JSON-RPC, but as a newcomer, I'd like to know what approaches have been adopted for routing JSON-RPC messages.  Are there any shining examples that are particularly popular? 

(And are there any examples where the routing information itself uses JSON syntax?)

Thanks in advance.

For LSP (Language Server Protocol) we've had a need for a kind of fanning out of JSON-RPC requests. Two parties will communicate, but one might send the other a request that cannot be directly solved, but the receiver has several other parties over JSON-RPC that it can forward the message to for processing. When doing so, the request ID has to be changed to be unique over the new connection, and then when the response comes back, it is FW'd to the original client using the original request ID.
