I'm having trouble following. Could you give more specific examples of  
what you have in mind? Does your expansion imply new requirements, on  
top of either Ian's list or my list?

I don't exactly follow this either. By "hybrid web app", do you mean  
something running locally with some portion of native code doing part  
of the job? Assuming that is what you mean: I think hybrid Web apps  
are extremely interesting (and something Apple supports and encourages  
on Mac OS X and iPhone OS), but they should not be used the sole use  
case for any API that we wish to expose to public Web content. The  
reason is that on the one hand, hybrid Web apps are not constrained by  
the Web security model, and on the other hand, they are always free to  
break out of the sandbox with native code, or capabilities specific to  
a particular runtime. For functionality we expose to the Web, there  
should be at least some justifying use cases that are pure Web apps.
