You can do some really fun things interfacing asterisk with IO control equipment. We use Opto22 Snap Brains and asterisk for various purposes. Opto provides some nice linux API code examples to interface with their units. I have a 3D tube laser cutter interfaced to asterisk so that someone gets called or paged when the cutter runs out of material or an error occurs, we also control air compressors with asterisk, and can check on various equipment status.

Someone else replied that they are going to use * to control their entry gate system by cell phone. Nice.

Thanks for the examples! While reading over at voip-info.org, I found the auto-dial feature that can be combined with .call files. That should be perfect for an idea I had -- use cron and POP3 to check my e-mail account for any new messages from the transit authority... if there are any, dial/ring home phones at 6am and playback a message to check e-mail for possible morning commute problems. Not quite as good as drunkdial though  :)
