  No, I mean *all* of the logic has to be in unlang.  Don't use the realm module at all.

	if (User-Name =~ /^([^@]+)@([^@]+)$/) {
		update request {
			Stripped-User-Name := "%{1}"
			Realm := "%{2}"
		}

		if (Realm == /my.realm.name) {
			# ... more checks on Stripped-User-Name...
		}

		update control {
			Proxy-To-Realm := &Realm
		}
	}
