I prefer "selective" over "conditional" for this because the latter is too
broad: it could refer to *any* condition -- client source address (as in the
"Cricket" version of "views"), time of day, phase of the moon, whatever -- or
combination of conditions whereas "selective" implies more to me that only a
very narrow decision is being made based on a very small, very relevant number
of parameters, possibly only one, e.g. the zone in which the queried name is
contained.

Lately I've been leaning towards "per-zone forwarding" which is totally
unambiguous.
