[maemo-developers] Gizmo Project, Wifi Walkie-Talkie, Wifi VoIP Telephony, P2P VoIP - kind request

[From: John Holmblad]

Darius,

you might also want to look into what Meraki has done with single 
(802.11g) wireless mesh radio systems/products.

    http://meraki.com/


They recently secured additional VC so their www site has been upgraded 
along with their products!


Best Regards,
