Taking into account Jose Alberto and Benjamin
Burgess's input RE DLing & caching import files, sure,
great, but what's the point?  The point of resolving
paths blah blah is that files declared in the
<import>ed "resource" can be located.  Thus if the
whole context of the import file isn't also
downloaded, nothing will be accomplished.  I think we
should allow import to work as it always has or in
some extended manner, but basically we can start by
importing arbitrary resources and failing when an
attempt is made to resolve a file relative to the
location of a non-file import.  Then perhaps we can
examine how to allow resources to declare a context in
some manner.  This might involve the use of the
nearly-forgotten ResourceFactory interface.  No doubt
I have missed something, but at least dialogue is a
good catalyst to expose such...

Just out of curiosity, how many people other than
Peter and myself have ever started to modify <import>
to allow non-file imports?  :)
