I just want to pass along the best of seasons greetings and thanks to all of you who have worked and continue to work so tirelessly to develop this terrific product. Yes it's expensive. Yes it runs only on proprietary and also expensive units for a small segment of the population, but it is so cool and so accessible and I want to express my appreciation for all of your efforts at developing this system and comtinuing to upgrade it with intelligent input from so many users. With best regards, Jim
