Any of you worked with one of these, http://www.mouser.com/new/beagleboardorg/beagleboneblack/?gclid=CLCs4pCi-bgCFY6k4AodgGUA1Q

One of the guys on the DC423 list uses one to monitor his home-brew system. http://www.10101brew.com/brewery.html

Secondarily, I'll want to trigger some kind of bell (ala Pavlov's Dog). I'd really like an HTTP interface I can initiate the treat sequence. I can do all the monitoring elsewhere (front door activity, neighbor dogs in their yards, etc).
