* Ability to make a web-based mail interface that has access to the actual  
files that my local mail client has.

* Ability to make a web-based audio player that lets me play the audio I  
already own (but with a different UI accessing different metadata), which  
have been filed by iTunes in a set of directories on my local drive.

As I understand it, your list is just a restriction of Ian's. I am not  
sure if this requires an extension of Ian's list - I am listing the things  
I am actually trying to do or know of people actually working on, before  
trying to get the requirements for each different approach.

No, I mean a web-app running as a web app, which assumes that other  
applications, some local, will want to use the document.

For example, I use several different applications to interact with images,  
with PDF documents and Documents in Word/OpenOffice formats, depending on  
what I am doing with the document at the time. I would like to add to that  
range of applications the ability to use a web-app without having to  
maintain separate copies - synching is even harder than managing my file  
system.
