Hiya

In our mesh platform that is used to support emergency responders, we use
an underlying
11s layer, leveraging the authentication/encryption capabilities, and then
use OLSR on top
to provide the routing and reporting/managing we need.
Sitting on top of 11n and Openwrt, it just works, and its stable.  We use
it to carry voice, video
and data across sites.
