This is a key point, we're getting way off topic.  Web apps accessing  
the "raw file system" is wrought with completely different (and much  
more difficult) concerns than we've been discussing, and is completely  
out of the scope of getting persistent LocalStorage working in an  
agreeable manner.

For this first foray into persistent storage for the web, I am -  
reluctantly - on board with the proposal of make a user explicit  
"save" like action part of the permanent LocalStorage experience.

I would *NOT* be on board with the spec requiring anything about  
"where the file goes on the filesystem."  I have never been convinced  
by the argument that users always need to be in charge of where in a  
filesystem directory tree every single file on their computer needs to  
go.

I'm a huge fan of the "my mom" litmus test.  To my mom, the filesystem  
is scary and confusing.  But using the browser to manage browser- 
related things is familiar and learnable.

To take Jens's suggestion further, user agents on ANY platform should  
be allowed to turn the browser into a "shoebox app" that manages its  
own data.
