It takes care of NAT/Firewalls, so you can sit on the airport if you wish and share something you work on locally. Even if it's your own home network, you'd have to go through the process of forwarding ports, have a static local and external IP, configure either a web server or a local proxy. I'm in no way affiliated to ngrok, I just think it's an awesome piece of software and use it regularly.

Are you sure about this being possible on airport provided networks ? My experience with airport networks is that pretty much everything is locked down and you can't set up anything from the airport.

It'll work from everywhere that allows an outbound connection. You're right there may be issues if you can't ssh out, but most airport networks I've been on has allowed ssh. It'd be a good idea for them to support tunnelling over SSL too, though.
