I would just do what you're doing now, which is to use the existing
exchange.  That lets the message broker do the work of duplicating the
message as opposed to making nova send the message multiple times.

Perhaps using another exchange would make sense if it made ACLs easier
for ensuring that an application can only get notifications, and nothing
else on the nova exchange.
