Correct me if I am wrong but isn't Hadoop moving towards the Avro IDL for full 
RPC (in either 0.23 or some later version)?

i would love an IDL, plus that modern serialization frameworks such as 
protobuf/thrift support versioning (although i still have issues with different 
versions of thrift not working nicely together, argh why is that). the only 
downside is perhaps that they are a little slower than writables.
