You'll want to load the window manager from an http url instead of the mojo: url
so that you don't end up with 2 copies by accident. :)  That won't happen to you
hear as-is, but if someone tried to connect to the http url instead of the mojo:
url, it wouldn't end up mapped and you'd start a second copy.
