That would be a fantastic looking WB if it were brought over to work properly on Vista and Win 7 Snowie!
I somehow doubt that'll never going to happen, Thomas, at least not based on Ian's reaction to this thread:

[02:11:08a] <voo> ick

I wouldn't rule out a future release if someone took on them the task of updating it. I'm sure Ian would give his permission.
And no, it won't be me. After all these years of skinning, SKS still scares the hell out of me.....
