It actually isn't that hard, but it is tedious and big. Once we get ipc and uts it will probably be the namespace to merge. I have the basic code sitting out on a branch. Getting the little things like sysctl, sorted out are the primary problems. At the same time we don't have to solve the problems for the network namespace now. Just don't expect it way of in the indefinite future, either. Eric
