A nit: dwds probably needs to be integrated with hostapd as there's some
work involved that's best in a long-running application and I can't
imagine anyone using it w/o some form of security. Having hostapd
handle this would also simplify configuration.
The integration work is straightforward and would be a good project for
someone trying to learn about the wireless facilities.
