Was just visiting when i read this article:
http://thehowzone.com/how/D70-Remote/3
Made me think of an article i found about two week ago on forum.dpreview.com
This guy took his D70 apart to remove the original IR blocking filter in front the detector to increase the infrared response of the DSLR.

Amazing!!
