2) The string can be considered a solid object when stretched to its maximum, ie no more stretch is possible. So when one end is pulled, the other end immediately moves too, and is therefore 'faster' than light. But this is not truly going faster than light, as nothing is moving from end to another, it's just an object beginning to move.

Ah, but the cause and effect is then instantanious and faster than light. FTL communication via the cans and string?
