Kitchen paint?

I was talking with a professor from India about cooking, and he told me that in cold climates (e.g. Wisconsin) where one couldn't always cook outdoors they found it advisable to cook in a garage or other outbuilding, because the oils and spices that smell so good at first tend to adhere to the walls and become rancid over time. I know that some apartment hallways tend to smell pretty rank, and the apartments can be even worse inside.

San Francisco is experimenting with pee-proof paints that are hydrophobic enough to bounce urine (and other water-based fluids) back from the surface. I wonder what sort of surface you would need to keep oily droplets from sticking. Tile is easy enough to clean (but not the grout!) but oil still sticks. We don't tile ceilings (and they're hard to reach to clean), and cabinets and handles get begrimed and so probably a source of odor as well. We try to keep things clean enough in our house to forestall that, so I can't be sure about the source of the odor, but the surfaces seem the most likely candidate.

If the surface was oil repellant, it would be easier to keep clean--and maybe not wind up as rancid. If oil droplets wouldn't stick to the ceiling they'd drift down. It's easier to clean the counter and the floor than the cabinets and the ceiling...

Of course the devil is in the details. Would water droplets adhere better or worse to the new surface? How do you put on a second coat of paint later?

UPDATE: Oh, and is it food safe?

I don't know about the rest of it, but it's not hard to get a second coat of paint to stick even if you've got an oily film on the original coat. Just give it a fairly ordinary washing with a good detergent, and use a primer.
