Looking for cross-platform IPC

I'm looking for cross-platform Interprocess Communication library.
Currently I'm using Boost Interprocess, but it is too plain, only send and receive.
I need at least callbacks, and even better complete RPC.

I would avoided sockets, overkill and too slow for IPC on the localhost
