	Well; the VFS question, is trivial and also comes down to:

switch (desktop-fragment-vfs) [
	case GNOME_VFS:
	case KIO:

	ie. very similar, very simple, _no_ bogus/spurious g_assert_not_reached
paranoia. No combinatorial explosion, no odd orders of complexity.

	OO.o uses shared libraries and a virtualisation / abstraction layer
anyhow: most large, portable ISV's applications will do the same - it's
a madness to suppose they 'already' use some recent versions of Gtk+  or
Qt as their exclusive cross-platform layer. So it comes down to:

bool do_gnome_thing()
	if (dlopen("libgnomething"))
		... use it ...
		return true;
	return false;

	And an ultimate fallback to some raw-X OO.o underneath it all.

	Of course - currently for desktops like 'rox' etc. you will ~always get
a plain-X setup, since there is no good way to detect what toolkit you
want integrated with; and the hacks for using gtk+ are gnome
specific :-)

	So - claiming that no detection at all is in some way more desktop
neutral is just bogus :-) Good of you to cut/paste Mark's unhelpful
switch statement with some conditional compiles.

	You can write a program that will automatically discover new desktops
and standards and then integrate perfectly with them ? without having to
write code - wow ;-) I'd like to use that.
