Assigning programs to specific audio outputs in Windows 7

There's some programs where I can't set which audio device I would like to use (e.g., iTunes), forcing me to use Window's default and I'm wondering if theres some way I can set each application running in Windows 7 to use a specific audio output.

My googlefu has failed me but I'm hoping theres something out there as I couldn't think of any good search terms.

This post has a link to several programs, including Indie Volume and Virtual Audio Cable, that may do what you're looking for.
