Hi Esteban,
I hope you didn't give up waiting for an answer so long. Sorry!

Exactly

Not a view embeddable into another view, but any element can of course
be embedded into another element, on the same App.
For reusable cross-app elements you subclass a WebComponent. Prime
example for such reusable, standalone, highly useful component is WebGrid.

Exactly. Even better: subclass a WebComponent, because you'll get even
more standalone and Ajax-ified component at the end. And WebComponents
will be greatly enhanced in the future. See again WebGrid for example.

In this case you better make an App class hierarchy accordingly:
WebApplication
ContainerModelApp
ElementModelApp

This is the distinction, yes. WebApplication is for a whole web page, it
is therefore a root of a whole element hierarchy of that page. You
couldn't therefore embed a whole page in another page (but even that
works:). As said the standalone subclasses of WebElement/WebComponent
are meant for such embedding as you'd like to achieve. Another way is
WebApp subclass hierarchy. Yet another way is iframe inside a page, but
this sounds a bit hacky for your case.
