The new high power LEDs are recent technology compared to lasers.  LEDs also 
have proven to be better for communications.  I suggest the rules specify 
allowing any light not produced by thermal energy.  But then then that wouldn'e 
exclude fluorescent light? I think the rules should also specify a reasonable 
minimum distance instead of capable of 1 KM.  Even 1 KM with laser is to easy. 
Why not require both non mechanical modulation plus some sort of electrical 
detection on receive?
