I'll leave Anime Bite open for scraping once it can afford the extra bandwidth
If you do it the same way as imdb and let people either access the db itself or an xml version bandwidth is not much unless they are scrapping pictures. its the way to go.
People are eventually going to ask for picture-scraping, LOL. A lot of scrapedbs out there start out small, but eventually end up adding thumbnail, movie poster etc image-scraping support. But for now, if anyone is setting up a scrapedb specifically for anime, just text/data-scraping would be really good already.
Not saying it has to be implemented now, I'm just saying be prepared to scale eventually, because people
will ask for it.
