Thanks for posting this.  Some questions:

1-  What is the proposed way to get a FileWriter from an <INPUT
type="saveas"> element?

2-  In the sample, it appears that onwrite is used to signal completion.
 But is that called if the write completes with an error as well?  Or, is
onwrite only called if successful?

3-  How are the onwritestart, onwriteend, and onprogress events defined?

4-  It would be good to document when the "length" and "position" properties
are updated.

5-  Can seek throw an exception if position > length?  Or, is it valid to
seek beyond the end of the file?

6-  Can truncate fail?  I would assume so.
