[Ed]

How about over water with say 100m clearance?

ROC of the earth tends to cut into the freznel zone so your end points
need to 
be WAY up in the air for these sort of links... On flat ground with
about 15 
foot ground clearance (antenna height), 5-8km would be about the
limit... 
(IIRC)

ofcourse, if it is straight up you can go forever[1][2]... or at least
until 
the ethernet timeout limits are approached.

[1] where forever is a mighty long way.
[2] given a sufficiently high gain antenna. say, several times the
diameter of 
the solar system....
