I know this is an old branch of this topic, but since it generated
quite some interest on this list, I thought I'd share this excellent
article I recently found on double-blind vs. single-blind reviewing.
It addresses most of the issues that were discussed in this
sub-thread.
In brief, the editor of a prominent computer science journal
recounts his exploration on which way to go with his journal. The
journal decided to go double-blind because of its benefits (mainly
protecting less powerful researchers), but his journal has a very
detailed set of instructions (in the appendix) that do an excellent
job addressing computer science projects that are difficult to
anonymize, which I think are very much applicable to a wiki-based
journal as discussed in this thread.
