I believe that although there is no detailed agreement on packaged apps, 
there is an shared intention to support hosted apps in an interoperable 
way.  I would like to hear more about how the browser determines the 
full set of components to download and cache when "installing" a hosted 
app.  My understanding is that the manifest file isn't intended to list 
the app's components. The appcache spec is known to flawed and it would 
be good to get an update on progress on replacing it.

It looks like we certainly need a standard way to attach signatures to 
hosted apps, and this presumably is tied up to how the set of app 
components are referenced.
