I wonder how easy it would be to hook this up to dns tunneling software such as http://code.kryo.se/iodine/ in such a way that after the the initial ssh auth step, you would have a useful terminal that would be accessible even behind captive portals and the like?

I've used mosh over iodine, by simply having the iodine-server forward all of my packets via IPv4 NAT. I then set my client gateway to use dns0 instead of eth0. Works great!
