Note edge app request topic

HELLO GUYS,

I have a small question to ask!
Recently a friend of mine bought note edge.. The phone is superb, but what's even more awesome is the edge screen
he gets running update notification of news, sports score , time or even meetings!
i was wondering can we make app, which will run in the right hand side bar, with constant notification flow of news opr latest updates,even fb updates..
like the edge screen a bar with running notifivation ..
is it possible?
thanks
