Occasionally the question comes to my mind whether we can use PS3 as a graphics data pre-baking tool. In that way, we will be able to take advantages of several SPUs.
One thing I am not clear is how to store the result data. It wouldn't be a problem with PS3 DevKit, but I am not aware of any means to store data from normal PS3s. Since Sony blocked Linux support, it may be harder than before.
