Actually it all works pretty well, so I pushed it all into experimental,
including a new T-G .deb in the APT suite. Things to look for:
* That no network devices are present before T-G login.
* That they are present after T-G login,
* That the MAC spoofing feature is applied according to the option.
* That the "blocked network detector" runs if and only if MAC spoofing
is applied. If it's inconvenient to reconfigure your AP to block MAC
addresses I've attached logs that you can simulate certain scenarios
with (just `cat $file >> /var/log/syslog` as root).
Please let me know what you think!
Cheers!
