Once you can do that the killer app will be intrusive ads.

And those people who drive down the street blasting loud music (err, I mean "sharing their stereos")? They'll be able to share directly to the people on the sidewalk!

(I loved your comment -- I think we both know this won't be supported).

In Borderlands: The Pre-Sequel/Claptastic Voyage there's an enemy called an Adbug.

"While technically hostile, Adbugs do not directly attack Vault Hunters. Instead, they follow their targeted Vault Hunter around and beam a semi-transparent advertisement at them, which is placed in a random position on the field of vision, obscuring part of the field of view."

You can tell when you're being attackd by an Adbug because they beam audio advertisements into your head.
