Janine,
I really think we should rethink OpenNSD. When I was at LinuxWorld with Talli and Roberto one of the biggest objections to OpenACS was AOLServer. I too, have been waiting and waiting for 4.0 and it doesn't look like much is happening.
I would be willing to put some time into OpenNSD if the community thought it was worthwhile to go forward with it again.
Maybe we need another thread on this topic.
