Middleware for communicating with Flash Player via Flashticle and Django.
Setup a view at /gateway/math/multiply like so:
def multiply(request, m1, m2): return m1 * m2
Then in your Flex/Flash app you call "math.multiply" on a NetConnection pointing to http://domain.com/gateway/
Does not yet support authentication.
