Does anyone have any experience with the xmove package? Since I'm frequently jumping back and forth between local and remote X11 servers, I'd really like to be able to move running processes from one server to another. xmove is the only package I've come across that claims to be able to do this, but I've not been able to get it working, and I've gotten the impression that it's so hopelessly obscure that nobody maintains or supports it anymore.
So, can anybody suggest a more graceful solution, or perhaps point to some documentation for xmove that's slightly more in-depth than its manpage?
