Mindsensors.com has provided us with information on their new NRLink product for the LEGO Mindstorms NXT:

“News for those who have an RCX and looking forward to use it with NXT… mindsensors.com will be introducing a communication adapter by end of this month. This communication adapter, NRLink, enables 2 way communication between RCX and NXT. NRLink connects to NXT on a sensor port, and communicates with RCX via Infrared.

Your RCX robot can be a separate mobile robot, and communicating to NXT robot via infrared. Using NRLink, you can download programs to RCX as well as receive sensor events from RCX; in short, you can do all the tasks IR Tower can do.
