The Apache Thrift project is going to be more open to external patches
and development. While Google (as an entity) would love for protobufs
to get those kinds of changes, I'm familiar with the developer who
worked on the protobuf code, and he is NOT what I'd call an
"inclusive" Open Source developer.

Also, take a look at:
http://stuartsierra.com/2008/07/10/thrift-vs-protocol-buffers

On balance, Thrift is looking further developed, though with worse docco.

For a pure C version, I'd lay odds on that being possible in Thrift
more than protobuf cuz of the contribution/inclusivity thing.
