No.

Yes.
Tho', there are what claim to be NiCad/NiMH combo-chargers. Not many
folks in rec.photo.digital (see below) speak well about them.

Mox-Nix. NiMH have different charging characteristics/curves
than NiCad's. You want to get a "smart" NiMH charger, versus
a "timed" NiMH charger.

Using Google Groups, look back in just the last 6 months or
so for "NiMH". The digital camera folks are *anal* about
battery performance: charging, storage, use, capacity, etc. -- and
they all, in general, swear by NiMH's.
(I say "6 months" because these are all FAQ's that come
up every few days or so. You won't live long enough to
read _all_ of them. :-)
