I think a transparent tile would be the best response.  This will then allow
whatever background the client has chosen to show through.

However, I just looked at the t at h layer on the main OSM site.  That appears
to display "More OSM coming soon" tiles where infofreeway is displaying
black tiles - so maybe I should investigate how that happens before we make
any more changes.




I'm open for suggestions on this one.
