Interesting Idea. But the network would have to be deployed long before the desaster.

Only one uplink to the internet is needed for mesh networks. If configured correctly everyon can use it. So a single satelite uplink might be enough.

The freifunk-firmware has a package which cn be installed named "DHCP-Splash". If someone connects to the router with a wireless device the first time, the webbrowser gets redirected to a configurable url. this can be a usage agreement or anything else. It is highly configuable. This would really be anything you needed for your idea to work.

we're using them here, so it was easy...

There are separate mailinglists for such projects to... one is wlanware (about the firmware itself, it is linux-based, openwrt) and one is... wlan international or something like this. I'll need to take a look when I'm at home. There you meet people who are deploying such networks in remote areas.

BTW: can you tell more about your project?

God bless you
