You can also pick up one of these "As Seen on TV" Stonewave cookers at your local Bed Bugs & Beyond
for 10 bucks American and save all those outrageous shipping and handling fees they charge if you order it on line. According to their commercial, it can be used for lots of different microwave recipes, not just eggs.
You might be able to get away with an induction burner hot plate in your dorm room. I'm sure some chemistry major could figure out how to cook meth on one, but at least the fire hazard is eliminated. The only drawback is you can't use aluminum cookware on it, they have to be some kind of ferrous material. I use an induction burner plate at my client's facility to test recipes before they get posted on the company blog, and I found some relatively inexpensive "aluminized steel" pots and pans at a restaurant supply store, and cast iron also works well.
