@Korrd:
No past tense. We have 3 self-constructed working links, all of them in invisible infrared range and they all work for 3 years without any service needed. The longest one, however needs to be backed up by a radio link just in case snow or fog comes. Two of them are installed on the roof of our house.
It's a beautiful hobby, but REALLY time consuming, so I switched to Freelancer :-P
But we're getting off topic here...:)
