An agreement was reached last night, ahead of the UN World Summit on the Information Society, to keep the Internet domain addressing control under ICANN, which is under the nominal control of the US Dept of Commerce. A new group, the Internet Governance Forum, has been created to look at Internet issues. It has no binding authority, but gives other nations a place to discuss issues that have international significance
I think that while shared governance of the Internet is a goal to look forward to, there is no mechanism available right now to actually implement, so the agreement to me is the best thing for now.
Here are a few links to articles about the agreement that was reached
