While the current PDP goes a long way to improving the opportunity of those not able to attend meetings in person to participate in the discussion, many factors, possibly cultural diversity being principal, seem to inhibit wide discussion. So the participation is still by few.

We currently use the mailing list, jabber, etc. to try to make it easy for others to participate in the dialogue. It is not clear that more technology will help. Perhaps other two way voice channels such as Skype will lower the barrier to dialogue.
