I can't speak for the schlagelink's reliability, or Vera2's for that matter. I have a Vera1, waiting on my V2, but I don't see how V2 would be any different than V1, considering it is basically the same UI. I can currently set/delete codes on the schlage lever set. I can do the same with the quikset deadbolt. Additionally, I am using Vera for the following:

-scheduling lights as needed
-Control of my irrigation system
-Gradually turning lights on at sunset and off at sunrise
-Managing RFID (open the garage door when I get home, lock up when I leave)
-Manage Cameras - Pan/Tilt upon bad keycode at the shlages, turn lights on upon bad keycode
-Lock up the house at night
-Turn lights on after dark when doors are unlocked
-Operate scenes when activated at leviton scene controls
-using IP functionality on S70, operate any devices not supported through S70
