I'm all for the second option: full programming environment. But that is the first here (and with MS extensions to JS APIs in Metro applications...). And without any distinction between whether the app run locally or whether the UI and data are accessed remotely or any possible combination of UI and data access mechanism.

Hi,
WebIntents rather not... Those are about registering services to perform 
some common tasks. That is fine for clearly defined data and actions 
(and shared communication among two full fully-fledged application)... 
but way to high level. It takes time to put low level functionality 
together to make things work, but you can do a lot... (and there are 
always libraries for most common tasks). But with high level APIs? no 
way to bend those.
I ment something like
constructor FileAccess(String path)
   onstartload(event)
   onendload(event with cause of end (success or some error) and Blob 
object )
   onprogress(event)
   read()
   write()
where path in constructor can be HTTP address, FTP address, local 
address (c:\path\myfile.txt)
of course based on privileges on local side, on server side (based on 
used address)

but as low level as possible and as generic as possible (exactly the 
same functionality locally, remotely).

But we have strayed away a little bit  :)
