[Freedombox-discuss] mesh network [was: FreedomBox Testing 2012.0617 Image Published]

[Markus Sabadello]

Just wanted to comment that a few people here in Vienna have been
discussing
trying to hook up the FreedomBox with the local mesh network (FunkFeuer,
OLSR-based).

When we get something interesting working, we'll let you know..

all the best,
Markus
