Sorry to mess up the conversation between Markus and Raphael's but Raphael's
response came in just as I was sending my response to Markus regarding
scenarios A thru D in his previous message.

I just wanted to say that if the approach you guys are working on with
Raphael gives any wifi client (no ad-hoc, no olsrd) the ability to switch
between accesspoints without losing VoIP connection (as Raphael was
suggesting in his initial email) then that would be all I'm looking for,
assuming it could work in case of VoIP.

Thanks!
