What happens if you tell a repeater to broadcast an <iq>?

The naive outcome is that all the recipients send you an
<iq type='result'> directly, each with an ID that you've never heard of. 
That will mess with most client libraries -- at least, the ones I've 
seen; they expect IQ-results only to IQ-set or get, with matching IDs.

Conservative proposal: declare that you can only broadcast message or 


"And Aholibamah bare Jeush, and Jaalam, and Korah: these were the borogoves..."
If the Bush administration hasn't shipped you to Syria for interrogation,
it's for one reason: they don't feel like it. Not because you're patriotic.
