Can't wait to try it out. For all you (us) Canadians, try this site:
http://www.geobase.ca
for Canadian DEM data. I haven't dug around this site much yet; so if anyone else has, please post your experiences.
(Oh, he he he ... DEM2TOPO mentions Geobase directly. I wasn't using DEM2TOPO at the time I posted this!)
