[zeromq-dev] Presence notification

[Alexander]

Hi Again,

I was just wondering if there is any mechanism in zero mq which lets
you monitor which subscribed clients queues or topics have. This would
be used mostly for monitoring, but we also have some use cases where
the sender makes sanity checks to make sure there is a receiver of a
message. This could of course be implemented on top of JMS, but it
would be a useful feature for what we are doing.

Best regards,

Alex
