Xpra: GNU Screen for GUIs

Anyone here use xpra and wouldn't mind showing it off at the library? I've found a couple gui programs that I want to keep running all the time, and I don't want to have a "server" running at home, nor keep my laptop on 24x7.

So I want to run them on a remote server, and simply peek in on them when I need to use them. They need to continue executing when I'm not looking though. And I also don't want to have a Window locked in another window like rdp or vnc would do. I want full desktop integration.

FreeNX was a nightmare last time I went down that rabbit hole, and this time I found xpra and it looks like it might do the trick!
