This was first posted here on Bitcointalk but we saw the chance to promote this project on Rugatu and take advantage of the influx of new users that find out about Bitcoin through it. We pledged a small amount at first to incentive any developers research it, and hoped more people would pledge in the future for having it completed.

The bounty on Rugatu is still active and all funds are kept in escrow, but we don't know for sure if the bounty is still going here on the forum. Guess Obsi should comment on this again.
