Not layered "on top" of HTTP, but dependent on HTTP to open a

a wiki would be better than google docs, because it would have
history.

I've created a site at  http://bwtp.wikidot.com
You can join at http://bwtp.wikidot.com/system:join
and the password is MustHaveMeta

I've not yet moved the document over.
