When Adam Laurie stays at hotels, he says he can hack his way around paying for premium TV channels, the minibar and phone calls.

What's more, by connecting his laptop to certain modern hotel TV systems, Laurie says he can spy on other guests. He can't look into their rooms (yet), but depending on the system he can see what they are watching on their TV, look at their guest folios, change the minibar bill and follow along as they browse the Internet on the hotel television set.

To tease his fellow guests, he can also check them out of their room and set early wake-up calls via the TV.
