Subject: a simple wireless mesh network

Hi,
I am studying wireless mesh networks and wanted to play with open80211s.
As a part of my study, I want to demo, multiple nodes on a mesh
network and analyze the traffic in wireshark

Unfortunately I don't have many physical nodes so I'm looking for a
way to emulate them.

So far I've learnt that vmware and virtual box don't support virtual
wireless network adapters.

Any other suggestion that would make creating a wireless mesh network
for study purposes quick and painless?

Thanks a lot,
Joel

http://wireless.kernel.org/en/users/Drivers/mac80211_hwsim

plus network namespaces, on a very new kernel where that actually works
(like current wireless-testing)

mac80211_hwsim claims mesh support...
