Has anyone ever heard of a crazy interpretation of the original trilogy where Obi-Wan is really OB1 and a clone?

Well I'm the worst Googler ever, because after years of searching today I found two links in like 60 seconds.

The theory is basically that Obi-Wan Kenobi is actually the transliteration of the alphanumeric identifier OB-1. The "Old Ben" we meet in Star Wars: A New Hope is actually the clone OB-1, who moved to Tatooine to watch over the young Luke Skywalker after Anakin's fall to the dark side the death of the real Ben Kenobi.

The best source I found has several notable attributes (note: it published on the web in 2004 and so vastly post-dates my original hearing of the theory in 1998) :

• Obi-Wan is a strange name, even for the Star Wars universe, and when compared to similar phonetic spellings for R2 and 3PO it's almost duh obvious that Obi-Wan might really be OB-1.
• It explains why the Alex Guinness character would change his name to Ben Kenobi, since Ben doesn't really make sense as a shortened form of Obi-Wan and Kenobi is an uncommon enough name to make it a crappy alias.
• It makes much more sense to clone Jedi, who are bad-ass, than Jango Fett, who is cool but no Jedi.
• It eliminates the need for the odd plot points required by the actual Prequels: hiding planets, secretly commissioning clone armies, and implementing intricate political machinations to foment civil war--all of which are elegantly taken down in the 7-part Red Letter Media review of The Phantom Menace.
• It explains why Old Ben has no memory of R2: OB-1 doesn't remember R2 because it was Ben Kenobi who knew R2 and not him. (Of course his bad memory can be ret-conned as feigning ignorance, but there is no rationale for Ben to to lie to Luke.)

The brief synopsis of how this idea would be woven into the prequels is that there is no secret clone army; instead, the Jedi are intentionally cloning themselves to keep up their numbers in the face of some threat. However in keeping with the Thrawn trilogy, cloning and the force have an adversarial relationship and cloning, force-sensitive people in particular, leads to mental weakness and instability in the clones.

This weakness makes these ersatz Jedi particularly susceptible to the Dark Side, which leads to large numbers of them being recruited by a Sith Lord and ultimately to epic Jedi-on-Jedi battles, including the killing of Ben Kenobi by his apprentice Anakin as part of Anakin's fall and transformation into to Darth Vader.

After Ben Kenobi's murder, it is OB-1 who has Leia taken to Alderaan and who takes Luke to Tatooine to be raised in the desert while he keeps a distant watch.
