I’ve seen a number of articles in the last week or so, detailing the game that Boxee is playing with Hulu (Hulu keeps blocking Boxee, Boxee makes a change to get around this blockade, rinse, repeat).
I don’t know the Boxee architecture in any depth, but it seems like the answer is to simply set the User-Agent to appear as if it is MSIE, etc and then have the client (i.e. end-user) fetch the actual video. Hulu then immediately has no way to identify who is a user coming to their site via a browser vs a Boxee user.
Or it is more complicated than that?
Also, Fred Wilson tweeted the link for the Windows Alpha of Boxee the other day. You can get it here (requires sign-up)
