Thought I'd take a look at how this worked. My first question is: why
are we sending stanzas to the repeater using <iq/>s? Why can't I
create a repeater, using <iq/>s of course, and then begin sending
stanzas directly to the repeater which then forwards them out to

Looking at the examples, it looks like the repeater service is giving
each repeater a JID. Sending stanzas to it directly ought to work.
Perhaps something like:

One problem is that all of the management use cases in the XEP would
probably need to be changed so that repeating <iq/> stanzas is
simpler. This is easily changed by making the repeater service's JID
handle all management requests for individual repeaters.
