Thinking ahead to 1.7... there will be some blocks that I'll want to blacklist for certain permission nodes... namely the Piston. I understand that WorldGuard already have a blacklist based on GROUPS? I am however requesting a blacklist (or whitelist) based on permission nodes. Example: pluginname.piston pluginname.redstone I wanted to get this out in requests to see if such a thing already existed. We may be doing it in house for our server/coding team.
