So, why not explore it. Properly. On this list. This list has key knowledge of the issues, yet has failed to focus that into specific alternate proposals that I have seen. I would encourage list members to work out some more formal alternatives and post them in a suitable thread. It would be far better for the next working group to be able to be sent 2 or 3 more structured options between "do nothing" and "kill entirely". Stephen
