I've actually tested this against MessagePack.

Original file is csv with base64 encoded fields and gzipped: 73554863 bytes
Msgpack file with no base64 encoding and gzipped: 64226388 bytes
protocolbuffers file no base64 with PDU and gzipped: 63470582 bytes

The msgpack solution was faster to decode and encode though, and it's also significantly simpler code in both erlang and Python (which I tested).
