battlefield-3
I noticed that in my battlelog (listed below my platoons) I have a veteran status for BF3 and BattleField Play 4 Free.
The bar represents your progress towards the next unlock in that weapon group. The more you use a certain weapon class, vehicle, etc, the more you points you will earn toward an additional unlock in that category. You can see a more detailed view of this progression in your battlelog profile:
I can get the overlay to show up in any Origin game, but having the name be proper is another story...
Here's what you have to do, I can confirm that this works for me (the overlay showed up in-game):
If you change "Origin" to "Battlefield 3" in the Steam Shortcut, it'll show up as such in your friends list. However, this means every Origin game will show up as Battlefield 3.

From the Battlefield Wikia:
I'm not certain how one logs into the Veteran site to register other games, as the link provided just redirects to the BF3 site. Some folks apparently have 10 or more Veteran Points, and supposedly it's possible to make your veteran status show on your dog tags.
