This is how you call it...

<%includeOutline ("http://dropbox.scripting.com/dave/worldOutline/states.opml")%>

And this is what it does...

<%includeOutline ("http://dropbox.scripting.com/dave/worldOutline/states.opml")%>

Don't build any mission-critical apps with this right away, because there will likely be some breakage here.
