Ideas : geo-tagging e-mail

Now this idea is around the hypothesis that there are are these sect of global people who are on the move, traveling to atleast two locations globally within one week. and the other user group being the mobile email users.

and so when they are accessing email when on the move, they make this metal note of the context they are in when they are reading that email. so if there is an automatic geo-tagging of the mail that happens one can start searching mail based on locations and contexts.

this is just a thought and my hypothesis cud very well be wrong
