> DNS tunneling

I've done it a bit (using iodine[1]) and while it obviously depends a lot on the DNS server they're using, it can be surprisingly fast. I think I got over 300kbps regularly, which while not great for video streaming, is more than enough for HN and such.

iodine in particular tries to use some less common DNS record types like NULL, which might support up to 65kb/reply, falling back to more common if those are not supported, so you can get decent download speeds.
