I looked into this a bit recently and discovered that the FAA offers this,
it's called the "Aircraft Situation Display to Industry" (ADSI) feed, and
it's free to businesses if you sign a letter of agreement with the FAA. (I
have no idea what the conditions in that letter are). It's managed out of
the John A. Volpe National Transportation Systems Center in Cambridge, MA
(which is coincidentally within sight of my office where I sit right now),
but I haven't been able to find anything more specific about it online.

I have to confess: after seeing the demo of Flight Explorer at the Expo, I
was tempted to actually purchase a Microsoft product (as FE doesn't run on
any sane environments). That's never occurred before.

If someone had a web or UNIX equivalent...
