I'd be interested as well. And since all the one-click-hoster stuff is a lot of hassle, I'd be willing to offer my upstream resources (about 1MB/s at least) via (S)FTP to hopefully make things easier.
Maybe we could also setup some kind of forum-internal site where we could host all the preserved audio tracks, custom versions, etc. Before anyone screams about piracy: none of this would be necessary of the labels would do their damn job right: to really provide any movie in its highest quality.
