Yes, IR splash is very messy for the receivers. The actual receivers are
very poor when compared to RF filters. They can not differentiate between
50 and 55% of IR energy, as to discriminate one of two IR splash at the
same time in the same room, as RF receivers do.
If xmiters should be isolated, then IR is not the best choice. They are as
dumb as if you try to differentiate a 74HC00 from a 74HC02 in the dark.
