Gtk+ 3.2 will let you run any application in a browser (Firefox 4 only) thanks to the new HTML5 gdk backend. That means you'll be able to run GIMP (a free open source Photoshop type app), Gedit, a video editor or whatever, remotely (or on the same computer), using a web browser.
This a significant step forward in the evolution of computing, development, and the browser. The possibilities are endless. More so when Microsoft catches up.
