About BF3 and private servers, its almost free to rent a 24 or 32 player server, me and 6 colleagues of mine have done that and it costs me maybe a pint of beer for 6 months. The only problem is that if you password protect your server you will invalidate the servers Ranked status, which will is sad for those that have not yet unlocked everything... A solution for that is todo like we have done, keep it public but restrict the number of players so it mathces the numbers of friends playing, you might have to kick some people which will make the server unpopular in the end.
I think its stupid to call head tracking cheating, sure it gives you a small advantage, but like others have pointed out its a small advantaged compared to a fast rig.
A good advantage is to have the game installed on a SSD, you will load faster and that means you will be able to pick the best vehicles for your self before everybody else. I always get the helicopter this way

It only works on maps that let you preselect vehicles though.
But I wouldst call 3D a cheat, as long as the games do not have proper 3D support it will be a disadvantage with 3D, at least in first person shooters, its much harder to aim in 3D because today games display the sights for both eyes. In real life you look down the scope with one eye and the other eye is used to spot enemies. And games that do not have sights and only display a cross hair are impossible. The enemy is 200 meters away and the cross is displayed at Z = 0
