Thanks Chris. Yes, he's a long time user of ViEmu. He posted about it almost a year ago, although the original post is only available through google's cache now for some reason:

George Reilly, core contributor to vim (the guy behind most of the Win32 port) is a ViEmu user too:

And of course many, many other hundreds of smart developers
