Google protocol Buffer Codec

[Jannick Bitsch]

Hi

The easiest solution is to wrap all your messages in a 'union type' as
described in this protobuf tutorial:
http://code.google.com/intl/da-DK/apis/protocolbuffers/docs/techniques.html#union

Alternatively you will have to manually prepend some kind of command id to
identity the kind of protobuf message being sent, but unlikely to be worth
the trouble.
