Free X server using Cygwin X86

I've used Exceed's X server for years, and I like it, but it costs hundreds of dollars. Slashdot has a thread about a free X server: Cygwin's XFree86 4.2.0 on Windows XP . Slashdot notes that this runs on Win2k, not just XP. There appear to be two primary problems: first, you can't run a Windows application window next to an X window, as you can with X servers like Exceed or Hummingbird. Second, you can't cut and paste between X and MS Windows. (The latter one is a bigger hassle, I think.) [Slashdot]
