I don't think that they need to deal with caching.  And in looking at the ib_at 
code, I think that caching should be removed.  A more generic SA path record 
cache would work better IMO.

I would rather see an interface similar to the caching mechanisms in place for 
verbs, with calls like ib_get_cached_path(), etc.  In any case, I think that we 
should defer adding caching in an initial implementation, and design an 
appropriate SA cache separately.
