Given that hostapd needs to be started with a configuration file as an
argument and not an interface like wpa_supplicant you need to add a way
to add multiple configuration files. The conf_file variable is
currently hard-coded to /etc/hostapd.conf, if you add another one like
hostapd_conf_files="" and iterate over it, that should do the trick.

But I'm not sure how to handle the pidfile, or how to name it..
