i got the impression that the "real" mapping types includes
transformation functions -- i.e., we have data in both state plane and
lat/long (UTM) and they need to play nice together. some more details
would be nice -- there are free packages out there to do the
transformation at the application level (search for PROJ and gctpc for a
couple of pointers), but nobody i know of has needed anything like that
enough to actually put it in the database itself. i think it would be
interesting to put out there exactly what you need to see what isn't
there, what can be worked around, what would be a good target for future
development, etc. i've had a few "wouldn't it be nice thoughts" about
similar things, but it's always been easier to workaround because as far
as i can tell there's not a whole lot of interest in those features.
