You're bringing back some good old memories for me Brent!  I used VTP a
lot in my last job and it produced some wildly beautiful product and
exciting fly over animation abilities (among other things).  Ecologists
especially liked the function allowing you to draw/digitise onto the
terrain in 3D mode.

We had Python scripts that did all our dataset prep for us, and if my
memory serves me right, we even had ways of converting the digitised
stuff back into a shapefile for use in our other apps.

Binaries are available for download for most platforms.  Then you
probably want to get a terrain model (just one big download) and put it
in the right folder.  Other than that it's pretty easy to get started
with WMS or file datasources.

Thanks for the memories :)
