UPS Tracking by email

As I was taking a look at the progress of my tablet to Motion I saw that you can track UPS packages by email.  Just send an email to totaltrack@ups.com and include your tracking number in the body or subject (you can include up to 25 tracking numbers in the body with no subject to track multiple orders).  A couple of seconds later you get an email response with just the overall status of the shipment (i.e., not the detailed stop by stop tracking).

I just thought this was kind of neat.  Of course, what would really be neat is tracking by RSS.  By including a tracking number on the subscription URL it could look up the status and push that out.  It could be added as part of the MY UPS system (or whatever they call it).  That way you can check all of your packages via one RSS subscription.  It could have a setting that just pulls the general status, or one that pulls and updates for each stop along the way.
