This is really cool. I've thought about how a host-proof app might be built, but not very seriously. I actually have a pretty simple project coming up that'd benefit from it, too. Maybe this'll motivate me to experiment. Any resources/reading you'd suggest, or have you mostly been figuring this out on your own? edit Ah, I see you've written a bit on it yourself (http://corte.si/posts/security/hostproof.html http://corte.si/posts/security/hostproof.html). Time to go exploring! As far as the actual app goes, I have only one real gripe. Being used to Vim, I expect i to add before and a to add after (with I adding at the beginning, and A at the end). Not having i/I do anything confused me for a moment.
