Not sure how helpful this is...as it depends on your messaging platform. We're a Lotus Notes/Domino shop, and we've been using an app called Showtime to push apps/icons to our users' devices. Most of what we push are custom contacts databases (i.e. Company Directory, contact lists for certain groups), but I'd imagine it would push whatever needed to be pushed, even just a browser bookmark. Works like a charm, and is configured & used directly from the Notes Client.

It's not the newest thing in the world, but it still works (we're on Notes/Domino 8.5.3 & BES 5.0.3)
