I forgot about the DNS querying of wikipedia. Probably could've used that to entertain myself on my flights over the holidays since I'm pretty sure gogo inflight passes DNS through.

Anyway, I'm a big fan of piping things into xargs. xxd is a terminal-based hex editor. It can convert both to and from hex to binary. I also use 'pgrep -lf 'partial_program_name' a lot in place of 'ps aux | grep partial_program_name'. 'pkill -9 partial_program_name' searches for and kills all processes matching the string.

If they allow DNS out you can use their Internet for free via iodine: http://code.kryo.se/iodine/

I run an iodine server for myself, you can get free Internet at quite a few loginpage WiFi routers with it in airports, cafes etc.

ssssssh ! When proxying over DNS becomes mainstream, it'll be shutdown !!

interesting that there's an android package.

Could it turn your old android device into an HTTP tunnel?

+1 for xxd, great for debugging purposes e.g. analysing serial output from socat (also mentioned by another commentor below).
