Add-on Bukkit to Xenforo Bridge

I've seen some bukkit plugins, but none are up-to-date, is there a possible way to have a Bukkit (minecraft) plugin to make them login with their forum account? (If they have one) For example when they are in the game, do /login <password here>?

If anyone wants to do this, you can release it at whatever price you think is good, if this is even possible. If this isn't possible without a Bukkit plugin, let me know and close the thread if that's the case. Thanks, good night.
