Recommendation on external permissions

I have a website for my mc server, and I want to be able to manage permissions on it.

I'm trying to think of the best way to connect it to the server. Any recommendations would be appreciated.

At the moment, I'm debating between these options:
1) Rewriting the permissions to use the database behind the scenes. I like this option for the control, but not for the amount of work it would take to integrate and manage the permissions.

2) Reading and Rewriting the yml permissions files, when ever the website interacts.

3) developing a plugin that records the permissions (as a copy) to the database. Then regularly checking for updates on the database, and using the internal tools, like PermissionsBukkit.

4) developing a separate SocketServer as a plugin, and a client into the site that can can change the permissions live.

Options 2-4 all retain the current yml/permissions setup/management. and are my preference.

I had tried process 1 before, because I don't fully understand how to work with the current permission system, but it became a little complicated to manage, and though I think I could do better on a second pass, I think I should give the current permissions structure a chance to be learnt.

Or perhaps there is already a plugin to help this, that I am not aware of.

Not 100% related to what your talking about...but somewhat.

bPerms has a web interface. Take a look and see if that will solve your issues.

 

make your own plugin, that gives and takes permissions to the permisable
