This is something a third party did for us.  I don't know all the details behind the library, but I do know that there is a patch to Qt to enable it to use our library instead of it's normal routines (this is for 4.6.2).

The patch to Qt is to use our library.  I'd be happy to share the patch to Qt if you are interested, but I don't think it is very useful generically since the licensing of our library says it is only to be used on TI devices (A third party license restriction).  Thanks for the offer though.
