Was just hackin' around on Google and stumbled across a reference to an Aerotech electronic forward closure kit (EFC-1). Looks sort of interesting. Uses a re-usable glow plug for ignition and apparently a timer set for after motor burn out. Looks like it went the way of the Dodo though. Anybody seen one? 2009 is the intro date. It's on their info page here: https://www.aerotech-rocketry.com/news.aspx?y=2009
