a nicer way of doing this would be to write a defun in emacs

my-load-file

so - it loads a file into a buffer - if the file has certain
traits that encrypted files do (ie: GPG headers) pipe it
through gpg file (mailcrypt does this nicely). 

and also write 

my-save-file

which does the opposite - and maybe we keep track of what files have to be 
encrypted.

C-x C-f calls my-load-file
C-x C-s calls my-save-file


of course emacs needs to be patches to only put its temp files in 
an encrypted loopback and we index them so we know where they 
are related.

  A disciple of another sect once came  to Drescher as he was eating his
morning meal. "I would like to give you this personality test", said the
outsider, "because I want you to be happy." Drescher took the paper that
was offered him and put it into the toaster, saying: "I wish the toaster
to be happy, too."
