user sends e-mail, and that e-mail is added as a goal.

Epic:

user sends an e-mail to a notification address; that e-mail is added as a goal.

This will require some kind of server to sync the local jfdi files, so it's a very long term objective.

another idea:
User can directly add the JFDI comment in the subject line like

j -f "foo" --tomorrow

where the response is sent to the user via e-mail.

This will help the user to organize her JFDI stuff without leaving her mail client, if she does not have access to her remote files.
(an alternative would be a web interface to do that)
