Gtk 3.2 Will Let You Run Applications In a Browser
An anonymous reader submits this intriguing tidbit: "Gtk+ 3.2 will let you run any application in a browser thanks to the new HTML5 gdk backend. That means you'll be able to run GIMP, Gedit, a video editor or whatever, remotely (or on the same computer), using a web browser. Just imagine the possibilities!" At this point, says the article, it's only possible with Firefox 4.
HTML5 is still a draft standard and in common usage it usually refers to a bunch of stuff like an in-browser video codec, WebGL, DOM data storage, canvas, geo location data support, etc. - almost all of which are not uniformly supported across all "HTML5" browsers - and that's especially true for IE9.
