Yes, this is just what I'm thinking too, though I'd like the option of binding
different CRYPT tags to different keys or passwords.  So, I could have
WORK_CRYPT, HOME_CRYPT, etc., and each would have its own separate protection.
This would allow multiple people to have their own private regions within the
same org-mode file.

allout.el goes a long way toward providing all of the above, I just wasn't
fond of the mechanism (I tried porting it straight to org-mode one day, then
stopped).  For one thing, I want to use my GnuPG public key for encryption,
not a symmetric cipher.  That needs to be configurable.

I should be able to create an external module for this that does not affect
org.el at all, but just adds keybindings to org-mode-map and after-save-hook.
