Can you do a collaboration with, or hook to, NoEntityGrief?
I love the way NoEntityGrief protect my buildings from mob vandalism without "cropping" creepers of their explosions or otherwise affect mobs ability to harm players. I would like to be able to protect certain areas (like villages or buildings and such) with NoEntityGrief. While letting “nature take its course” outside the area, making the game more dynamic and interesting.

In 1.0 some of the EpicZones info should be accessable to other plugins with ease. The author of NoEntityGrief would need to then hook into that data.

If you want to have them contact me, iId be more than happy to work with them. to make that info easier to access.
