It's an example. You could make them for anything. I never had time to get around to it, but I was thinking of one to map out cubicles to switchports. We already sort out switchport SNMP/LLDP stuff to know which IP/MAC/Serial is on which port. CM/SM registrations tell you what IP is to what extension. if I could force users to key in their cube number, I'd have cubes-->ports-->IPs-->Users
You can use push notifications too - like send a message that the Browns scored a touchdown or whatever other thing you feel like advertising on a phone display. Be creative. Ultimately the 'new' way is the Vantage APIs to use the Android tablet phone for more webpage looking apps.
Think like office building/mall lobby phone, you could have an app with a directory for stuff in there. Not that you couldn't do it with speeddials existing already, but you could if you wanted to. Or, something like the 'app' could send a message to the webserver that pushes to someone else using a PC and not an Avaya phone that you're there for an appointment.
Or if you didn't feel like doing what everyone else does for security to make the guards turn a key in a lock or beep a cardreader at every floor to do their rounds, you could make an app at the push of a button to track that.
I'm not saying that any of these are good ideas, just ideas of what you 'could' do. But considering most users in an office environment never used them before and there's other ways to implement most ideas, they typically don't get much traction. You're right about hospitality being a big one though - it's a market where you can have new users all the time in front of these phone and who wouldn't do 'normal business' stuff with it. Instead of speeddial to room service, put the menu on there. And if you were going that far today, put a Vantage tablet and have a beautiful picture of the cheeseburger instead.
