Avahi doesn't "merge" domains in your searche path. I.e. when using
something that is domains-aware (such as the new avahi-ui dialog) you
can select them from a list, but that is all.

avahi-discover only browses for services in ".local" by default. You
can use av avahi-browse "-d" to browse in other domains.

Yepp. Unfortunately most GUIs don't support clean domain
browsing. avahi-ui does. But not much else.
