I thought I read in one of the posts that there was a 4mm or thereabouts threaded hole in the back of the empeg. How about putting some sort of eyebolt in that hole, then using your relay-driven locking plunger to secure the eyebolt? I haven't got my empeg yet, but when I do I plan on doing something like that. Probably set it up so that you have to turn the ignition on to remove the empeg.
