I think you can do a lot better than that. Laser Communications
Inc in Lancaster, PA (+1 717 394 8634) sells Infra Red Laser boxes that are
supposed to be usable up to 1km in all sorts of weather conditions. As of
about a year ago, they had a system that ran at 10 Mbps for US $14k. We
havn't tried one yet, but I've communicated with a few people who have them
and say they really do work, even in rain, fog, etc.
