Something that may require some thought if you want to do this is how you handle import/export of documents with embedded scripts. You'll need to be very careful not to fall to the "applications that download additional code" rule there. This happened to Codea (http://twolivesleft.com/Codea/Talk/discussion/comment/14504#Comment_14504 http://twolivesleft.com/Codea/Talk/discussion/comment/14504#...), and afaik they still haven't managed to get their project sharing feature re-approved.
