What about a fanny pack? Also, most of these PSK's seem to be geared toward 'personal' survival but I bet we will end up using our tools and skills to help others (family and friends) more than ourselves. For this reason I always have a keychain size CPR mask and keep my CPR cert up-to-date. You can get these from your local redcross for cheap.

look here for a picture

I like the altoid box a lot though. I have a heart shaped one but it's still full of mints.
