Yeah its possible, I had a powder magazine article from like 8 or 10 years ago about a dude in Vermont that would remove the edges on his skis and he would ski frost at his local resort. The magazine is at my parents house and I wish I had it now because I would scan it for you.
^^^ i remeber that article. it was in skiing mag i think.....i remember the guy saying that it was " all about lubrication" or something. so yea its def possible.
