This is what the current spec says about setting the tag manually:

"[A consumer tag] specifies the identifier for the consumer. The
consumer tag is local to a connection, so two clients can use
the same consumer tags. If this field is empty the server will
generate a unique tag."

I haven't come across a use case for this myself, but it does allow
you to use a well known name if you can be sure not to re-use it in
the same connection. I guess you could just send off the consume
command and just ignore the ack if you were sure that the subscription
was definitely going to suceed. Saves you a line of code - which may
appeal to the effici-o-nados out there :-)

Any other takers?

HTH,

Ben
