All,

So we have arrived at a destination that's mutually inclusive re. 303 
indirection. Basically, an additional technique that uses 
Content-Location as the switch. Nice, simple, clean, and shouldn't break 
a thing, as long as people stop producing "old school" RDF resources.

In addition, I think we've also triggered a POWDER fix that's been long 
overlooked.
