Yes, I would and would not ;-) The technology in use is called XPFE. For a full (graphical) overview, see http://mb.eschew.org/1 http://mb.eschew.org/1 It is different sorts of XML (XBL, XUL, RDF, DTD) controlled via Javascript and styled by CSS running on top of a C++ runtime. The components, the runtime exposes, can be accessed directly from within Javascript. Most of the application specific stuff is written in the XML+JS+CSS domain. There may be the one or other app-specific support library, but in the end, they all run on top of the same xulrunner binary.
