Up until a month ago we also had the wallet and android development support donated by RoboGuy.
He unfortunately is tied back up and will not be able to participate in development until his current project is completed.
Just out of curiosity, about how long until his current project is completed? Is he planning to be back after that?
I am not sure how long the project is running; however he did say until the project is over - reading between the lines it does suggest that he may be back once he has completed it.
