I have a "role" within our club - the duty clerk. It's the one role where there must ever be only one duty clerk logged in at any given time otherwise some mischievous person could play havoc with our flying log sheets.
Ideally I'd like to restrict the login for this role to a specific machine situated in our launchpoint control vehicle.
Our Aware app is running on a VPS in some datacentre somewhere in the world and our ISP can't (won't) give us a fixed IP address.
Apart from changing ISP's is there any way I can find out programmatically, a machine id, mac address or something else unique so that I can achieve the restriction I need.
