Hello, it's me, I have the same coffee problems as your wife. A few things that really helped, used in increasing order of desperation:
1. Buying a temperature-adjustable kettle and making coffee at 185° or so instead of boiling. Bonus: I think the coffee tastes better anyway. I recently moved and couldn't take my fancy kettle with me, so now I pour cold water into the boiling kettle until I guesstimate I'm at 185. I guess this tip doesn't work if you're using a Mr. Coffee machine or whatever.
2. Giving the mug a really good blow as soon as the coffee is poured.
3. My wife bought me a few mugs that are much wider at the top than the bottom, meaning there's more exposed surface area and the coffee cools off quicker.
