Solved Obsidian destroyer with TNT

What I want:
I'd like to have a plugin that allows TNT to destroy obsidian with a configurable amount of hits. And I'd like water to make it 50% more difficult to destroy obsidian. So no 100% protection if you have water. The obsidian blocks after they have been destroyed shouldn't drop.

Also if you could add a similar breaking ability to enchantment tables and enderchests, it would be great. I have tried to find a plugin that does this but I have only found 2. One is inactive and doesn't work with Spigot 1.8 and the other isn't free. I'm sure this would be a huge success if someone created this plugin.

Ideas for commands: No commands needed for this plugin.

Ideas for permissions: No permissions needed.
When I'd like it by: As soon as possible.

We all need this so badly! Nothing works anymore if someone could do this for me, I could donate some cash if it is good

 

ObsidianBreaker, that I threw together right now, has just been approved at BukkitDev. Will probably add some more advanced features in the future.
