Internet Access for Mac in case of Kill Switch

Does any one have any expereince using Dahinia on a Mac or something similar? Its a PC app for creating a local-mesh type network. (see below)

From: http://dahinia.com
"Daihinia™ is a tool for WiFi. It turns a simple Ad-Hoc network into a Multi-hop Ad-Hoc network. Multi-hop Ad-Hoc networks offer a higher level of flexibility than the usual Infrastructure Mode: in Infrastructure Mode all the computers have to be in the range of the Access Point, while in Multi-hop Ad-Hoc networks they have to be within one another's range."

I'm not usually a "doom&gloom" guy, but I like the idea of being able to stay connected even when the govt thinks it's not a good idea.(see below)

Cheers
