The mere *presence* of a TCP connection to a peer does not indicate that
peer is active in any way.

Therefore, assuming the naive case where the underlying transport is
exclusively TCP, and you have a PUB socket with X SUBs connected to it,
implementing a 0MQ socket option to return X on the PUB side would in no
way help you with "detecting network failures".

It may of course help you to do "other fun things" :-)
