Apple states on their support site that you should never operate the powerbook or ibook with the lid closed, but htey don't say why. Probably the heat thing. I'm using an iBook as an internet server and want to let it stay awake while the lid is closed, an also to prevent my 1 year old from banging on the keyboard so I may use the paperclip method.

Here's more info from http://docs.info.apple.com/article.html?artnum=25801 after a search on 'ibook lid' in the Support area:

What might prevent a computer from going to sleep or going into an idle state?

If Apple DVD Player is the active application, the computer will not go to sleep when left idle.

Other applications, such as some fax software, can also prevent the computer from going to sleep regardless of Energy Saver preference settings. Tip: The Mac OS X 10.3 Panther faxing feature does not prevent a computer from going to sleep or entering an idle state.
