Have you guys checked out Opera extensions (built on W3C Widgets)? It
gives you an alternative way to think about the problem:

1. The widget can continue to run happily in a self contained environment.
2. Hooks are provided that allow communication with a web document
(via injected scripts).

But sure, embedding zip packages into web pages would also be
interesting and project's like Apache Wookie have done it
successfully. Natively supporting such a thing, however, has had
limited interest.
