MultiSeat computing - keeping your licensing legal

I have been watching nComputing and Fiddlehead as they work to earn some of the K-12 market. As I have tested both and heard from other schools that have done the same, I would say that nComputing has a much larger market share, but it is because of marketing budget, not because it is a better product. I stood outside both booths at NECC and it was apparent that Fiddlehead customers are much happier than nComputing customers. When I overheard a Microsoft rep say that Fiddlehead is totally legal when it comes to licensing of XP, or Vista, or 7 but nComputing is way into the "gray" area, I began to realize that M$ is helping Fiddlehead without even trying. Here is a link from ChannelWeb that has Fiddlehead as the #6 on list of top 25 new technologies for education. nComputing used to be on this list. http://www.crn.com/it-channel/218401323;jsessionid=QTZT5YD0YWN3MQSNDLPCKHSCJUNN2JVN?pgno=6
