We used a special link-level transport protocol over infra-red to use Styx to talk to a programmable Lego brick from Inferno. It did run-length encoding, and possibly some other compression scheme. All you need is a transport protocol that reliably preserves content and order. It doesn't need to keep record boundaries, although transport protocols are sometimes simpler if you do, working with messages instead of a raw byte stream. It doesn't need to be an Internet Protocol (ie, there doesn't need to be an IP layer). 9P itself will multiplex many clients on the same connection to a server, so you don't need a higher-level multiplexing protocol using ports etc. In fact, using attach names, you can have several different server trees served on the same connection to many different clients.
