I think the cat's already out of the bag on that one :/

*CENTRAL-REGISTRY* could be depracated, but as long as it people are still 
using it it all of the new layers on top of it aren't very robust.

While I'm by no means opposed to incremental API improvements to ASDF I do 
have the feeling that before tinkering with things too much it would be 
better to make a clean break and call the new design (whatever it may be) 
ASDF2: the installed base of ASDF is way past the mythical 12 of "make". 
;-)

In either case: it turns out that the ASDF API _can_ express what I needed 
to express. Essentially:

  (defun sysdef-priority-search (name)
    (let ((*central-registry* (list '(my-systems-pathname))))
      (sysdef-central-registry-search name)))

  (push 'priority-search *system-definition-search-functions*)

Kudos to Dan for making ASDF the extensible flexible beast it is!
