Yes, exactly. Right now it takes about 10-20 seconds until the

In my tests I use ath0(master) and ath1(ad-hoc) on wifi0. And there
comes the next evil trick: Everything has the same MAC-adress on ath0.
If you used an alias, the mac would change from station to station so
we would wait until the arp-cache for this IP times out and the
connection continues. If we applied the same trick with using same
mac-adresses on an adhoc-network, bad things will happend, because in
this case, the same mac-adress would be present in the same network.
