Not sure how many there are. Some of them used to be on the Spleen, but they were taken down, presumably because of their general rule of "no Disney." I have the Great Mouse Detective one, but never got any of the others.
I know that TLM, Aladdin, TLK and Pocahontas all showed up in "Mr. Whorse's Workprint Film Collection" - the Rapidshare links still show up on FileKnow, but unfortunately they're all long dead. :(
