no I don't, (I don't have the hardware nor did I test it)

The word "Generally" implies so.

But a referral on thier website: 

https://www.open-mesh.com/store/categories.php?category=Who-is-%22Open%
252dMesh%22%3F

refeers to ROBIN  not to 802.11s

Further ip-mesh has to be done in ad-hoc modus to have egal peers.

Building a wifi network infrastrucure would not be a mesh. But aslo 
would allow dynanic (routing with B.A.T.M.A.N / Robin / olsr /
lvrouted / ospf)

Unless use 11s you can't have an infastrasture mesh.

Infrastructure means a master and a client. In mesh you have equal
peers.

Atheros depends on a hardware abstraction layer. Depending on this it
can do monitoring / client / ad-hoc /master. 

For client mode you can substitute infrastructure/managed 
For master mode you can substitute hostap / ap. 
 
Then there are possible combinations 11b/g/a and maybe s/n.

ip-mesg (olsr) ends after 5 hops (20% per hop loss, not usable traffic
after 5 hops).

Maybe you some free ones from FON, create a benchmark (dbs). 

Anyway, I have a FON board and will come with test results later for
bridging-mode :)

I don't have high expectations for ip-mesh nor from radio-mesg. So even
if open-Mesh has 802.11s I would not use in class.
