Two other possibilities: (1) It's merely an independently produced cryptosystem disguised as a "leak" to save its creator the trouble of asking experts to analyze it for him/her.
It strikes me as rather foolish to mail off anonymous copies to several individual recipients (Matt, Perry, Tim, ...) in addition to the list, if S1 is a real leak. Why aid the traffic analysts by firing off multiple messages through the remailers ? BTW, the code has been posted to Usenet by a Frank Falstaff -- look for message ID <40b8tk$cj4@news.xs4all.nl> in sci.crypt (Wed, Aug. 9, 1995). His article refers to a message ID (namely <40b50l$oa8@utopia.hacktic.nl>) that differs from the message ID of the copy sent to c'punks. So it looks like there was at least one additional recipient. That's a minimum of 5 originals so far.... -Futplex
