Andy, we rigged a universal remote with high-output LEDs, and took multiple IR boards and swapped out the IR receivers with those sensitive to different carrier frequencies.

We found that at closer ranges, our high-output remote could be jammed by regular remotes and vice-versa. Our high-output remote had better range than a standard remote, so past a certain point, normal remotes had no effect. However, we found a very popular, normal, bone stock, single LED remote with a 62 foot range, which is already pretty "super" IMO =).

We also found that a remote using a 36kHz frequency can jam one using a 38 or 56 kHz frequency, and vice-versa.

There's been a lot of discussion on CD regarding IR jamming, and how best to handle it.
