Because my laptop doesnt have a video card and when im on the website i see people who i want to talk to on the live map, plus i play minecraft on my other computer. I know its stupid.
Unfortunately, I am sure that this would use up huge amounts of server resources that could otherwise be spent on other things. ATM Justin is very busy working on some other updates... I am not even sure that this is entirely possible too because minecraft isn't programmed to do such thing It is a good idea, keep thinking of possible ideas.
