TypeKit has a lot of countermeasures to ensure that the fonts are used according to the license, and not by anyone who isn't allowed to or through proxy's or something. I don't know the details but had a run-in with this in the past, resolved soon by customer support. I'm guessing Adobe didn't care for creating a second serving system to serve up these fonts, or the licenses are still restrictive that it requires some added logic.
