I'm going to be flying on via Continental in the next few weeks and happen to know that they will have Verizon JetConnect on board. This has the nice feature of letting you get on various instant messaging services while in flight, but doesn't let you do anything useful, such as ssh to a machine.
Therefore, I want to hack together a little proxy for ssh using Perl, but wanted to solicit some suggestions before taking a stab at it. I'm thinking that PoCo::Client::MSN, PoCo::Server::TCP, and PoCo::Client::TCP probably hold the keys to tunneling the data over MSN, but haven't even attempted anything this crazy before.
