Actually the IR link may work even when the RCX is not facing the IR tower.
If the range of both devices is set to `far', IR light reflections may be
strong enough to be `seen' by IR receivers. That's true only for short
distance however, say 3-4 meters. For me the IR link works even in an
adjacent room, but performances vary from case to case: ambient light,
object surfaces, interference sources... are important.
You may also check legOS (http://legos.sourceforge.net/). It gives you
more control and more power from the RCX compared to the standard firware.
That may lessen the demand for bandwidth, but this dependes entirely on
your application.
