Very interesting, Coyo...

Ronja is great, but perhaps 10 Mbps is too slow at today...

But 1.4 Km is very very good...

You can also to cross public streets with two PPP wifis configured as
bridges between two cable ethernet switches... It dont needs special
antennas or absolutely free space (it runs also with some trees in
between, and it can reach 100-300 meters)...

I have this with my neighbour and it gets 108 Mbps, ciphered: I see
his lan and adsl router and he sees mines, with some trees in
between...

To set up a very good and stable public DNS server you only need a
linux box with bind9.
