Hey coinme we are in the process of upgrading to the latest core as we speak.  Almost all of the issues we've had creating the mac wallet are linked to the old core. As far as merged mining goes we may look at implementing this; however, the coin is designed to be difficult to acquire.  If gold were easy to get then everyone would have it and it would be worthless....  The rapid adjustment of the difficultly was intentional.  Yes it sucks, but it was our intent to this to help stave off the pump N dumpers.  As soon as we get close to the update I will post here!!  Thanks for the info and keep any ideas and or requests coming!
