Bukkit

What is the enhancement in mind? How should it look and feel?
Jail players instead of banning, or custom commands upon player death.

Please provide any additional information below.
You could add an option to jail players instead of banning, but that would be quite complicated to do I think (or would take a lot of time) so the second part of the idea:
Add an option in the configuration to do a custom command(s) upon player death and return, so server admins can set alternative punishments.
For example:

custom-command: true
death: /jail {player}, /say {player} has died. RIP.
res: /unjail {player}

After the " , " would be a second command to run, this might be useful to have as well so we can set custom messages when someone dies that way.

I hope this will be added, mainly because of "compatibility" problems with Buycraft where a player needs to be online to get his package delivered, so he can not be resurrected unless he's online -.-
