This is certainly something we have always had in mind. However, for
"1.0" we just wanted to support the local case [1]. Supporting
pointing to an external resource is certainly something we could look
at: from the WG's investigations, it has obvious security implications
(i.e., what does it mean for a widget to get its content from a
website? does it mean that the origin of the widget is that domain?
etc. but I'm sure you thought about this stuff already as part of the
Google Web Apps store).

There is certainly few things restricting the working group
investigating this, and writing an extension spec that grants
<content> the ability to support a URI in the src. Also, a Robin notes
in his email, it is technically feasible to distinguish between a
'zip-relative-path' and a URI, so adding this extension in a separate
spec should be no problem... it just needs a good security policy.
