There are a few links in the mailing list discussion I referenced in my previous post (#4) but other than that, information is light. Seemingly WebKit can be compiled for the N800 by pulling the code from the main WebKit svn. If you are interested in WebKit for Maemo, take a look at the official WebKit project http://webkit.org.

As far as this new "OWB" browser is concerned, I'm not really sure I understand why sand-labs.org have seen fit to fork WebKit in order to develop a Maemo build when one already exists. It all seems pretty foolish to me.

sand-labs.org seems to be an open source incubator owned/operated/supported by an outfit called Pleyo (PDF Press Release). I suppose sand-labs.org is similar to Maemo/Nokia in that respect, however I've never heard of Pleyo and I'm unsure of where they intend to take this browser, particularly as they don't seem interested in contributing to the main branch of WebKit along with everyone else.
