CHUMP is the CHUnked Message Protocol. It is a minimal message passing protocol.
version 0
int16 -- version of the protocol (0x00 0x00)
int16 -- type of the message (user defined)
int16 -- tag (user defined, can be used to track responses)
uint16 -- number of bytes in the payload
byte[] -- the payload (arbitrary length array of bytes, may be empty)
CHUMP is designed to be a language independent protocol.

I started this project while developing an Android app with a friend. We were originally using HTTP which was far too heavy considering the small size and simplistic nature of our client server messages. CHUMP provided us with a protocol that is very lightweight in library size, data overhead, and speed while still being sufficient for our needs. CHUMP may be useful to you for another purpose.
