 This is more of an exploratory topic than a demand.

 Mike and I have been investigating the safeness of using flash on various
 platforms for TBB and during the tests on Windows found out that all of
 the Flash LSOs (i.e., supercookies) are stored in
 %APPDATA%\Macromedia\Flash Player\macromedia.com\support\flashplayer\sys\
 on Windows and
 ~/.macromedia/Flash_Player/macromedia.com/support/flashplayer/sys/ on
 Linux.

 In the testing on Linux, we discovered that it was possible to create an
 opt-out LSO called settings.sol which would prevent the creation of other
 Flash cookies (you can recreate one yourself by going to
 http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.html).
 It's easy to put this on Linux since we reset $HOME in the Linux TBB, and
 it is probably also easy to do it for OSX since we do the same thing
 there.

 Mike wrote a patch for the Windows TBB launcher (see here:
 https://gitweb.torproject.org/mikeperry/torbrowser.git/shortlog/refs/heads
 /appdata-haxx).

 However, in my investigations, I also discovered some Qt functionality
 that might do what we want in a saner cross-platform way:

 http://doc.trolltech.com/4.6/qsettings.html#setPath
 http://doc.trolltech.com/4.6/qdesktopservices.html#storageLocation

 Would it be crazy to try resetting this? If it works it would prevent all
 sorts of data from being written to the wrong place. Is it already in use?
 I looked through MainWindow.cpp a bit, but not extensively, so this may be
 redundant.
