[Joshua Foster]

I'm wondering if you could use an XPUB and XSUB socket. You know when to start sending when you receive a subscription.

To avoid the slow joiner problem, it looks like the preferred mechanism (correct me if I'm wrong) is to use a REQ-REP socket to send a synchronization packet from the client to the server at which time the server knows it's "safe" to start sending out data to the client.
