I've done this. It's a reasonably straightforward way to multiplex multiple endpoints over a single TCP socket, and it also gives you a framing protocol. It doesn't have a particularly high overhead (past the initial headers and such it's just a socket with a pretty lightweight frame header). You can find a library in basically every language and/or framework and they often deal with a bunch of other details for you.
