If technically feasible, that would be amazing.
An example of why it'd be useful:
My host recently changed my streams address, thereby invalidating all the links in the various directories which I'd accumulated, most of which I probably didn't even know about. The number of iPhones I had connecting fell from a steady 1,000 per day to less than one now.
If I knew where my listeners were coming from, I could contact the directories and update them.
