So, I started this:

I'd like to turn it into a setting that can support people randomly jumping in to play evil little goblins defending this outpost they captured against rampaging zombie hordes with multiple "Deputy" DMs (with reduced ability to edit main maps, but the ability to add new ones, and shuffle their subordinate party around between maps) keeping track of different aspects of the setting or taking care of a specific party. It would be kind of cool to get this little city going and really take the roll20 community aspect to the next level.
So:
1) More than one "DM" on the same board.
2) Different levels of "DM" power. So one guy can't get disgruntled and break everything.
3) Discrete player parties that can communicate in a general chat, but are individual groups as far as mic/webcam communication goes.
4) Always-on boards
How much of this is actually achievable, or would be easy to implement?
I'd really like to play with the idea of a persistent world, and see where we can go with it.
Infrastructure and available equipment can be the sole result of what goblin characters produce with profession checks. Parts of the city could be built up, expanded, or destroyed over time.
