Something else you might look at (although it it's Linux based, sorry guys) is the LART project <http://www.lart.tudelft.nl/>. They're using the StrongARM chip which allows for the processor to essentially shut down while not in use thus producing minimal heat. There are *many* other advantages to using their system in your situation. While the project is a work in progress, they do have working boards and free schematics. rus To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
