Block placement Logger

I'm looking for a none bukkit version of log Block which logs every block a player places and removes. Even though bukkit is great and all, with mods its becoming harder for me to maintain my server. I'm looking to see if there is one so i can revert back to a non bukkit server but still keep my anti griefing safety net.

Also if one doesn't exist where does minecraft decide to add stats for each block a player places. Since that would be a great place for someone to start creating code to makes logs of block placements. Since all it would take is adding a file writer that adds a new line to a notepad doc with the player name, location and block type.
