I need some more information to help you much. What is on the other 3 walls and do you want to just cover them, cover the brick front, or the whole house? Is it a full brick front or a wainscoat about half way up?
If you are looking for a stucco appearance, builders around here are using a stuff called finestone that is precolored, goes on with a texture, and is supposed to last a long time. It is a fairly new product and who knows what it will look like in 30 years.
I'm not so sure I personally would cover brick though.
