Hey there Roofdog
That's a heck of a list you have there. I may have to read it a few more times before it all sinks in... LoL
If it is of interest to you I'll be releasing a Integrated Index Page (IIP) pro version in the upcoming months. This version already has a calendar that's under construction. Calendars can be assigned to specific boards and there is a "master" calendar for the site itself. Users can also have personal calendars to store their private events in. Event additions can be moderated or not. Private calendars are of course not moderated since only the owner of the calendar can view their own events.
I still have plenty to finish up with just the calendar feature and your list really has some good ideas. I'll try and keep them in mind while I'm at it.
You can check out the calendar here:
