Yes. This is the core use case for the URI resolution stuff.

I would add a c15n type solution here. We don't have a protocol
but its a fairly simple idea....

Same c15n solution as #2. Essentially #2 and #3 are the same
functionally. The only difference being the actual reason why
you would be using some other copy instead of the authoritative one.

Hmmm... seems to be the same as 2 and 3 to me. I.e. you end up
doing the same thing except that the reason for doing it changes...
