Interesting - do you know of any service that does this? I'm curious as to how exactly you want it to work. Rereading your comment, I agree DNS and backups make sense, but upgrading the application itself still seems somewhat fraught. If your patch doesn't apply on an update, what should happen? Don't upgrade and send you an email? Do they upgrade the rest of the system it runs on? Do you want to be able to run other programs on the server as well, and if so, how would distro updates work? I think we disagree pretty fundamentally, but you've got me curious now about how your idea would work, and I'd like to hear more.
