Bukkit

I am using the ss and it works fine.

I have gotten a new plugin called build in a box, which and fold in and out a building, with WorldEdit use.
I would like to ex. make a house, place the sign on this house and make it contain the name of the new owner.
We never know who or how many ppl will receive this box.
The "biab" plugin can automaticly set private doors and chests in the building if present, so why not place a playername on the second line of a sign somehow? Can this be done?
