Actually, it would be easy enough for someone with electronics and
microcontroller experience just to build a new receiver. You typically record
the IR signals on a PC, figure out how they're coded, then program a
microcontroller to decode those signals.
You'd want to check with people in the Mindstorms groups. Something similar has
surely been done already for interfacing with the Mindstorms units, which can
use IR to communicate with each other.
