[MLB-WIRELESS] Optical Data Link

[Richard]

What do these things use then? IR LEDs or something?
I think they would be susceptible to some interference from the Sun and 
heavy rain/fog, so not completely noise free, but at least you don't 
have to share with phones and microwaves. :)

You might be able to convince someone like Jaycar to set the kits up, 
especially considering they're completely open source designs.

... ok are they REALLY called Korunas? Sounds a bit too much like 
kahunas to me.
