I've not actually used them, however, but I do like the radios (802.11g, 
same as whats in the 1200 units I do have) and they are outdoor 
mountable.  This is 802.11g 54mbps gear.  I'm pretty sure you can 
configure the root bridge to choose a channel based on local 
interference, but I'm not sure if it will change channels if it needs 
to.  There is a command to ask what the interference is on all channels, 
too, however. (dot11 dot11Radio 0 carrier busy, and then show dot11 
carrier busy)

Output looks like this:
Frequency  Carrier Busy %

    2412          1
    2417         10

The integrated antenna should 'just work' for across the street.  The 
injectors for these units use an interesting dual-coaxial (75ohm 
F-connector, even !?!!?) design that also brings ethernet to the unit. 
You can ground at the unit and the entry point and the injector includes 
lightning protection to protect the inside gear and power infrastructure.

My guess, for a bridge, is that you can just setup wpa-psk with a long 
key for security.

Looks like $850 per unit with power injector (AIR-BR1310G-A-K9-R).  They 
have a kit for doing the mounting and outdoor stuff, but the equipment 
is mostly standard except for the mounting equipment, so you'll need one 
of these too. (AIR-ACCRMK1300, $160-175?)
