I've thought about building an API that integrates Twillo with the HN API. Lots of planes/airlines have free messaging wifi, but not free wifi. But, if you could text a number and get the top n stories, then read the comments and perhaps the text of the stories (?) would be pretty nice way to pass some time. Alas I haven't done it yet...

I think most of them pass DNS queries. You could do HN-over-DNS.

How do they pass DNS queries? Just UDP on 53? If so, you could just proxy instead of relying on the DNS protocol.

I would guess only port 53 to the DNS server that the DHCP server gives you.
