Just to continue Fergus' line of reasoning, Type Reflector (CVS module:
type-reflector) does the same thing. It has three different front-ends
(Gtk#, System.Windows.Forms, and Console), that you can select by using
either a command-line argument (--displayer=NAME) or by setting an
option on the type-reflector.exe.config file.
Actually, the .config file supports an ordering of preferred front-ends,
so that it will try each one, in order, until it finds one that works.
