if they've got a whitelist for UDP 53 you can openvpn out nicely.  i
get hit or miss success with this; most national hotspot services use
a DNS proxy for UDP 53 traffic, so you can try OzyManDNS and bask in
the gratuitous inefficiency of your side channel transport... :)
sadly, ICMP tunnel is rarely useful these days either.

Now you've hit upon what I dislike about some of these techniques. As
interesting and impressive as some of them are they lack a certain
potency. If they reliably achieve their goal they are slow; if they have
better throughput then reliability becomes an issue. That is an
oversimplification, of course.

Bah. Who cares about that. Our governments have proven they do not
respect the rule of law; why should we?

Fantastic clip. Anyone, at the end of watching it, should ask themselves
"What am *I* going to do about it, personally, now, today?"

This is a call to folks who might be waffling: violate that NDA, release
secret information, backdoor your code, pirate out valuable software and
licenses. Find a way to put it on the net, and do it.
