My sensation is that SLAPI calls can occur in far more places than overlay
ones; the latter are confined to after a database is selected, and along
the path from front-end to backend and vice-versa.  SLAPI can also act
before database selection.  Everything else occurring after database
selection should be possible with overlays as well.  Note however that by
using back-relay in its current implementation, one should be able to
interact with the request BEFORE real database selection, at the price of
unnecessary DN rewriting because one needs to mask the real naming context
used in the real databases.  Maybe we could simply add a stack of overlays
BEFORE the database is selected?

Ando.
