i was actually going to start a project ,similar to the Virtual WiFi project in
windows 7 which allows multiple wireless network connectivity, in ubuntu. I  was
unaware of the mad-wifi project. now i realise that my project is invalid
because you have already done it .but i have seen that most of your work is on
atheros drivers. i am using a broadcom network card. does mad-wifi support
broadcom? also i tried installing mad-wifi and was unable to . i keep getting
this error

./kernelversion.c:13: fatal error: linux/utsrelease.h: No such file or directory
