Let's go first for Tom's acceptable solution and, afterwards, let's 
demonstrate him that returning a path instead of only adding a revision 
could simplify things in the following ways:

-no need to mantain a path for revlibs, the hook takes care
-no need to modify my-revision-library to accept multiple paths
-no need to modify find-local-cache functions to look in multiple paths
-no need to do anything special for get --link as the hook would take care 
 of creating the revision in the desired directory and returning it

I see it very clear, but Tom's main concern, as discussed in IRC, is that 
you could corrupt the archives with bad hook returns. I think I could 
overcome that just checking that the path really belongs to the requested 
revision. It would make things easier, but he's still not convinced :(

I'll start coding this up and keep you informed.
