Actually, I've had a NeXT style Dock and menu system mostly completed for ObjectBar for over a year now. (sheepish grin)
Since moving to Macs to run OPENSTEP v6 (Mac OS X, in other words) I keep selling my Windows system everytime I build one up and have never finished it. Now that ObjectDock is finally out and looking good maybe I'll see what I can come up with, including some nice NeXT icons for XP.
OTOH, I hope my ObjectDesktop subscription hasn't expired yet.
Actually, I have NO IDEA what's going on with NeXus as I haven't been involved with Winstep since the early Spring of 2001. So you'll have to direct that question over to them now...
