Is it possible to have code awakened by a packet arriving at a given port similar to the "Wake when the modem detects a ring" feature in Energy Saver?

I understand the heat-constraint; is it possible to undertake a small amount of processing while the laptop is closed?

Anybody correct me if this is no longer true.

Your conclusion is right, but your reasoning is only sometimes right. Laptops go to sleep when you close the lid because that's what users expect. With some machines, if you have a keyboard and display attached, you can run the laptop with the lid closed (close lid to put it to sleep, attach keyboard and display, wake it up using the keyboard). That feature comes and goes depending on the heat properties of the machine. If the machine gets too hot when running with the lid closed, we disable the feature.
