[zeromq-dev] RPC implementation details

[mrevilgnome]

Howdy,

I'm in the middle of doing some exploring/prototyping and I was
curious how others implemented RPC on top of 0mq.  Initially I was
going to use 0mq as a transport for Avro or Protobuf, but then I
realized that by doing so I would sacrifice a fair bit of 0mq
functionality.  My current thinking is that I should use multipart
messages; a header which is the function name and a value which is the
protobuf serialized parameters for the call.  Initially I thought that
I might want two headers one of which would be used for routing
between clusters by function, but I figure that I can have nodes
register capabilities with a router.  Does this seem reasonable?  What
have others done?  Please poke holes if you see them.  Thanks.
