An anonymous source is claiming that Hulu.com and Apple will be launching an iPhone/iPod Touch compatible version of the site as early as this Thursday.
Anonymous sources tend to be inaccurate more times than not, but lending some level of credence to the rumor is that it appears that Hulu's base encoding is H.264 which would make such a version of the site at least technically feasible.
Hulu.com came out of private beta last week and is now open to the public.
Update: Silicon Alley Insider claims that such a pairing is not in the cards (yet) according to a Hulu.com spokesperson.
