communication between several Wifis shields 101 without Router ?

SurfingDude:
It looks like that in access point mode, only one client AT A TIME is supported.

yes, and that's not good...
I'm not so experienced, but how can the AP make proper DHCP if only one client is connected at a time ?
I think I'll be better off with an ESP8266 maybe (?)
I'm making experiments with the wino-board today and it look promising so far ... http://wino-board.com
