A better goal is to not bother with TOE at all, and just get multi-core processors with huge memory bandwidth :) Again, the point of my message is to have something _positive_ to tell people when they specifically asked about TOE. Rather than "no, we'll never do TOE" we have "it's possible, but there are better questions you should be asking"
