Bukkit

What steps will reproduce the problem?
One player PvP on, one off.
Player with PvP attack non-PvP player, but no damage occurs.

What is the expected output?
It acts as supposed.

What do you see instead?
Same.

What version are you using?
1.4.2

Do you have an error log of what happened?
Nope.

Please provide any additional information below:
I would like an "Attack only" mode, where only the attack portion of PvP is changed.
ie: If PvP:disabled, I can't attack players, but can still attack mobs,etc...
BUT: If PvP:enabled, I can attack ALL. Even players with PvP disabled.

I have a specific need for this mode. Please add it, but I won't be surprised if you don't. (maybe as an option in the config?)
Cheers. (:

FYI: I want this so I can have certain players be disguised as mobs, and have the PvP act accordingly. This can be accomplished by removing the player of his/her player status. I don't know how to do that, so an attack mode would be the only other solution I can find.
