What kind of extensions/changes to AppCache would be acceptable at  
this point? In a previous exchange with Ian, he declined to consider  
DataCache like extensions to ApplicationCache for HTML5, which might  
be the reasonable thing to do. I can of course put together a  
proposal, but it would be good to know from browser vendors what their  
preferences are in this matter.

I am open to the idea of incrementally evolving AppCache to be more  
supportive of DataCache requirements.
