-TODO: Is the GTK HTML backend in by default?: http://blogs.gnome.org/alexl/2011/03/15/gtk-html-backend-update/
+      The HTML backend called "Broadway" that renders in a browser 
+      by using websockets 
+      <ulink url="http://blogs.gnome.org/alexl/2011/03/15/gtk-html-backend-update/";>has been improved</ulink> 
+      but is still experimental. 
+      This potentially allows to either run your own apps on your server and 
+      access it from anywhere, and to put it on a public server that spawns a 
+      new instance of the application for every user. Note that this requires 
+      compiling GTK+ with 
+      <varname>--enable-x11-backend --enable-broadway-backend</varname> and 
+      setting <varname>GDK_BACKEND</varname> at runtime.
