I am able to read files from my file system from the browser.  For
example enter this into the Windows command line:

echo some dummy text > dummy.html
echo "<a href=dummy.html>dummy</a>" > test-read-file.html
test-read-file.html

and click on dummy when the contents of test-read-file.html appears in
the browser.

For me, it causes the contents of the dummy.html file to appear in the
browser.  I am on Windows Vista and I tried it in IE8, Firefox 3.5.5
and Chrome 3.0 and it worked in all three.
