i agree with the idea to make the movie site(s) more "p2p-international"
i. e. there is a site for the edonkey (
http://www.sharereactor.com/) - maybe you get some inspiration.
i think most p2p systems use a hash value maybe we can extend to some of them.
as for the movie details - for now i do not know how to extract them, but they are more or less open formats and maybe there is already some code available. if anybody is expert herein - there is no problem to share my code (it's rather undocumented) for further development.
