I'm not interested in having a binary driver but in simulation of mobile 
networks with virtual machines. By placing a virtual driver into the mac80211 
layer the sollution would be totally transparent for the clients, even for 
applications with Radiotap headers and Libpcap.
A central server would be connected to the userspace parts of the virtual 
driver and simulate connections between the VMs.
