Does anyone know of a way I can use Google Protocol Buffers .proto files with C++ on Maemo Fremantle on the N900? Presumably it would involve getting the protocol buffer compiler and libraries to build in Scratchbox and then getting the runtime libraries to work on the device (and then packaging the result up in the repos somewhere)

Specifically I am planning to work with Google GTFS-realtime data.

EDIT: It looks like there might be some protobuf stuff in extras but it looks to be old and un-maintained with no-one working on it anymore.
