If you ever hit the 15 machine cap, i would just say to go ahead and pirate it, I mean you already paid for it.
arkham city is worse, 5 machines, 10 installs per machine.
You're only looking under Securom, under GFWL they list GTA4 and Episodes as legacy titles, and they say this about legacy titles:
Legacy method: A simple CD key check. This still requires an Internet connection, but it does not tie the key to your account. This has an activation limit between 10-20 (usually 15), similar to the usual Microsoft products (such as Office). If you hit the limit, contact Microsoft support. With proper evidence they will give you a new key, but you are only allowed one more key. After that, you will need to buy the game again.
