I am putting this response to the mail-group as a whole, because I
feel that too often people get trapped into using projection systems
without a fair analysis of the needs of their application. A lot of
times UTM is chosen just because the user has heard of it or
a friend used it. A lot of grief results and often the UTM gets
bent well beyond its defined limits.
Flames, comments or questions welcome.

I couldn't agree more! UTM too often gets used as the "native" coordinate
system in GIS's, probably because USGS DEM's set the digital standard way
back when we all had 9-track tape drives. The only logical "native"
coordinate system for GIS is lat/long. Everything else is a projection
(said dripping with disdain and contempt).
