True, they're designed for Yale-lock type applications rather than high
security.  I've been looking for something suitable for a while.  I think
Abloy (http://www.abloy.com) probably
do something usable, but they never
did send out the info that they said they would... maybe I'll try again...

I'd rather buy a proper product than home-brew something with solenoids
etc, but if all else fails, I will try to motorise the bolt and lock
function of the uPVC doors... but that could be a long time away...

There are quite a lot of 'gotchas' in making a door secure, some of them
not obvious, and I'd rather not take any chances with that for now.
