Feature Requests: Unique URL for RSS feeds

It would be nice for each user to have a unique URL for his/her training feed so that training data could be incorporated into other websites.  If I'm not logged in to MapMyRun, then the feed doesn't know who I am and displays no data.  I wrote a script that displays a Flash chart of my weekly mileage on my website (chrisramey.net, click on Running).  Currently I use my own database to store training data, but I'd like to use MapMyRun to store training data, being thatMapMyRun is where I store my routes.

Or, possibly there are alternatives using the current setup...?
