Well, I tried using both the built-in iTunes broadcast and Airfoil, but the iTunes signal cancelled out the Airfoil signal. But it seemed like Airfoil was really trying to simultaneously send to the other Express. So my guess is the problem lies with the hardware, in which case, I guess I'll have to try using Nicecast and use both of the house computers. Tunes At Work is still in development because of a change in library information. Oh well... Thank you for your help, Jacob.
