Theo de Raadt co-created AnonCVS back in 1995/1996. He and Chuck Cranor from AT&T Labs Research published a paper in 1999 about it.
OpenBSD was the first open source project to make access to their source repository public to non-developers, before AnonCVS you needed commit access to review history, annotations and even checkout. OpenBSD had a read-only CVS tree even before their website was created in 1996.
There are no known prior cited examples of a project providing this level of transparency to the development process, most open source projects at the time only provided "snapshots" of development in the form of compressed source directory tarballs, excluding RCS files. SUP and FreeBSD's ctm(1) only let you merge "current" remote changes to a local non-versioned directory.

Threads involving OpenBSD can involve fierce downvoting so it's probably a good idea to be clear about what you're saying.
The site is now more political than ever and this just seems to fuel the "silence what you don't agree with" type voting, which I don't think is a good thing.
The pythonic tendency towards being explicit about what we mean to say serves us well even in prose. :-) I agree with the OP, it's a pretty neat engineering feat. I think the downvotes would likely have been avoided had that admiration been more clearly stated.
