This all depends on who "we" is taken to be.
A web indexing robot doesn't need to resolve tei pointers at all,
except to identify the remote document -- it then indexes the whole thing.

I don't follow this. Under what circumstances is searching a document for
an ID much more painful than using a cache? Is this for 100 MByte documents?
(which do exist, by the way, droves. No, like elephants, in herds)

Not sure what a VC is (validatable context??) but yes, they all have to

I think that should be application-specific.
You might provide a hash table interface to make it easier, though.
