My Aunt does this a lot. She has a mini-cake pan (eight loaf style cakes to a pan) and she'll make up mini meatloafs
Not sure why, but I hadn't heard of these before. Granted, I don't do a lot of baking, but reading that lead me to some interesting google searches, and I think I'll be picking some up. Mini cake pans are a pretty nifty idea for not only portion control but also baking faster. Same total amount of meat loaf, for example, done in 18 minutes vs. 75 minutes. I don't see a downside there.
