Poor choice of example - if I had a heating system that needed such a trigger it would take longer to get up to temperature than the travel time from 1km away, even by foot. For long range control I would be looking at internet or phone based systems like asterisk or CSD dialin connection. There does seem to be a market for wireless touchscreen home remotes, many of them very expensive. I doubt this market would accept a dongle - it just wouldn't look cool enough. If you can build it into the FR, or recase it to enclose the dongle, you may be able to sell into that market. You probably won't find any overlap between that market and this list though - we're by definition internet-centric and likely to build our own solution. There may also be some resistance to ZigBee's GPL incompatibility and IP policies. http://freaklabs.org/index.php/Blog/Zigbee/Zigbee-Linux-and-the-GPL.html _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
