I am wondering if it is possible for someone to write an iDisk application. I will be using Mobile Me in the near future and one thing that I would love would be to access iDisk files from an application so I could edit those simple text files on my iPhone and it would save it back to the iDisk in essence keeping everything in sync.

So basically an app that allows you to open files from your iDisk.
Hook that up with TextEdit on the iPhone to work on it
Then when it saves, it saves it back to your iDisk.

How easy would this be to accomplish?
