Since I've been playing with this the last few days, I'll go ahead and
answer; please keep in mind that I'm a novice, too, so I may not give a
complete answer.

Yes, that's correct.  If you use a PNG with an alpha channel (to date,
the only program I've found that fully supports alpha channels for PNG
is 'The Gimp' (http://www.gimp.org)), POV will automatically use the
alpha channel for transparency mapping.

The nice thing about this is that PNG supports separate transparency
values for every color in an index, so you can get some interesting effects.
