XWT: The Universal Client

adam_megacz writes "XWT is a GPLed 'universal client' -- an end run around the current state of client side OS lock-in. It lets you write applications that run on a server yet display their user interface on any client machine. Unlike VNC and X11, all UI operations are performed on the client, so it doesn't suffer from lag or freeze-ups when you lose your network connection. It also doesn't require a you to download/install/configure anything since the client is delivered as a Java Applet or ActiveX control (Linux native client also available). There are some cool demos on the site, including an email client and a widget sampler."
