In 2006 I created a Mashup using the Google Map API. 
Hosted the HTML pages with plenty of JavaScript on Google Pages, 
as well as the images (for icons...) and XML files.

Now, in 2009 Google is discontinuing the Google Pages service,
migrating users to the Google Sites service.
Problem: Google Sites does not support custom HTML
and not even inline frames (to circumvent that).

So....I am officially retiring my mashup.
Follow Up projects will follow....
