[zeromq-dev] Caution: Wire format changed!

Rather than negotiating the version, implementations can simply drop the 
  messages that have unrecognised flags set IMO.

It can be done, but it requires modifying the 0MQ codebase. Allowing for 
hooking in different protocols would be nice, but it would require some 
work on the hook-in API. Any proposals?
