Well, since any buff will allow you to tether to someone (and get a speed boost if they are faster than you) for a short time, it seems obvious to me that this includes shielding someone. The only question I have is how long you are able to make that tether last. Due to the lack of canned animations, I can also reasonably assume that you can ditch the tether and take over controls at any point you want.
As far as uses, keeping anyone alive, especially lights and people with low life is an obvious one. Could also be used to keep the high priority classes alive, which would be medics in most cases; if you end up dieing to keep them alive, they can just throw you a revive syringe and you will be back to 100% health in a few seconds. Protecting people who are completing objectives is another obvious one, such as people hacking or planting/disarming a bomb. Shielding civilians that you have to escort would be a nice addition, but I'm not sure if you can.
