TUN/TAP module for Linus

[Alex King]

I coded up a simple wraper around the TUN/TAP network driver, just to
see if I could do it :)

It could be used for the same types of tasks as the original TUN/TAP
driver, such as tunneling (VPNs?), bridging remote networks, network
protocol analysis etc., except in python now.

More info is at http://alex.king.net.nz/tuntap.html.  No documentation
is available, but I'll do further work to develop this if i get feedback
that it might actually be usefull to someone.
