Last year the wonderful Laurel Papworth blew us away at SBTUG with a presentation on Social networking.
In the course of her presentation she mentioned the whole mesh network concept (eg Meraki). I truly had tingles down my spine when I heard about the concept.
Thanks to Laurel for this post in which she highlights the news of mesh networks coming to Sydney real soon. See http://blog.freesydneywireless.com/
