Since Windows XP is basically Windows 2000 under the hood, and since the problem is being seen with two different to X servers, I guess it sounds like the problem is really with Xemacs and the long ping times rather than the X server or its hosting operating system. It would be nice to see if the problem occurs when the local machine is running Linux. Unfortunately, I don't have any easy way to do this test.
