This might sound silly but what about adding a list of DVD(s) an anime episode is available on?
I mean it might sound silly but it might, just might be possible that someone who saw this or that episode wants to actually *gasp* BUY an episode on DVD - then he/she would have to look up a DVD review and find out whether it is really worth buying, or he/she would have so search the net IF the anime is available on DVD already in his/her country AT ALL.
I don't really request a DVD review part (yet). But let's simply take GitS SAC. It is available in Japan on DVD up to EP 14 or something? The fansubbing stopped *gasp* and now everyone and his sister is desperate to get the missing episodes. Once the DVDs are releases in another country (most of the time that would be the US) it would be nice to get a notify that the DVD is available now (which might also be a reason to now look for DVD Rips but who knows maybe someone will actually visit an onlineshop and buy the DVD). And then maybe once the DVD release reaches a NEW (not yet fansubbed episode) everyone will jump back on the waggon and get those DVD Rips or the DVDs.
That list of DVDs could first of all simply encorporate the company who released the file and maybe a unique identification number if there is such a thing. If it is possible you could also simply find out how to hand over a search query to different onlineshops and query those shops with the Anime's title.
And of course that would be applicable for every country, that way you'd find out in how many countries an anime is already available on DVD.
Later on you could add other features like reviews of the Anime and such things, and maybe a rating. Maybe pages like animeondvd could be queried but maybe they won't allow that, who knows.
But since ONLY copying is not symbiotic but freeloading and actually (I guess) killing the stuff me all like we should try to help those people investing in our hobby to get their money back for licensing, voice acting and subbing.
*climbs off his soapbox*
Thank you
