I certainly don't want to know how to do it (I have no technical skills to try it anyway!), but I'm curious as to how easy this might be.
Whenever you hear about kids using msn messenger etc, you hear warnings about making sure you neve give out personal details to strangers.
However, by virtue of being logged into messenger and chatting to someone with ill intentions, how easy would it be for that someone to attack your computer and try and get personal details (eg XP log in names etc) from your computer without you knowing? If its easy, it makes the whole point about keeping personal details safe pretty redundant, doesn't it?
