I've been thinkin of buying a gadget called TV B gone. Here's the link on their site:

But then i was thinking that you can have a universal remote kind of an application on yous n900. So is there any application that comes with only shut down or starting options for tv's (or other IR controlled devices)?

If there is none then this could be a fun project. I would do it myself but i don't know how to do any programming..

So what do you people think about this? It would be great for simple pranks
