The OSM Binary Format is a proposed new format for getting data from the
API, currently partially implemented in an svn branch [1] (waiting for
TomH to get back to me at the moment about some implementation choices -
his todo list is too long).
The page you have found on the wiki is about some additional features
for mobile devices. In particular tile based requests which are cached
to reduce server load. The wiki has a link to the proxy code (renamed
osmgetbmap) in symbianos.org svn [2] where the development of this
started for use with WhereAmI.
If you want to just get a quick example of the format without installing
anything then symbianos.org also has a clickable map to let you download
a few OBF tiles [3].
Cheers,
Adam.
