With a tightly focused beam (light is easy, I don't know about lower frequencies), you can prevent interception except by very obvious physical devices. (e.g. Someone in a cherry picker truck.) You may be able to avoid the need to encrypt the link (and all the paranoia about key management, advances in factoring etc. that that implies.)

Key management problems? With someone across the street? You gotta be kidding. If you can't memorize the key (say with the S/Key key-to- phrase algorithm) and walk it across the street, write it on the back of an envelope, walk it over, re-key, and burn it.
