apparently apple noticed that the mod_rendezvous everyone was talking about was actually a pile of crap, and wrote their own. it shipped with the 10.2.4 update, and seems to work quite well. my laptop's web sites now show up nicely in safari.
more info (found via Brian Jepson's Blog).
oh, btw, this is a great example of how apple should have shipped it sooner, so they could have snagged the mod_rendezvous name, instead of losing the namespace land grab and getting stuck with mod_rendezvous_apple, which is much less cool sounding.
