You might want to think about using the Asynchronous AppleTalk protocol.

It's used by the Async AppleTalk driver from Dartmouth.
I suspect that it's spoken by several commercial products as well.

The protocol is quite simple; it just wraps a DDP packet between two framing
characters.  A 16-bit checksum is included, raising the total overhead to
4 bytes.  Framing characters appearing inside DDP packets are escaped; this
adds slightly to the overall packet length.

Richard Brown at Dartmouth College is probably the best contact:
