It's open source, someone just needs to write the C code.

Otherwise, right now, one could check in the config with the User-Agent
header.

On the other hand, afaik, all the storage systems that do replication
ensure compatibility only for the same version, and adding checks for
each mirrored packet can add to the processing overhead and affect
performances.

Cheers,
Daniel
