I came across a program that my father in-law would love to watch and I really wanted an easy way to share it with him.
I was thinking that if I could 'share' a program with another FIOS customer via the 'info' menu for a particular program. Then the other customer would recieve a small notification on their TV indicating that I have shared a program. When that customer selects their notification, they are taken to the program that was shared (assumes access to that channel). When that customer is on this shared program, the notifcation just changes to a small message indicating I shared it with them and then disappears after about 5 seconds.
I think content providers would really like knowing customers can have a social feature like this as well.
