I'm not that familiar with playmaker but what kind of integration would you be looking for? I guess you would want some way to start hosting or connect via playmaker? Maybe just need a custom action script or two? I've used playmaker in the past but not very extensively. If you can describe in a little more detail what you're looking for it might be something I can look in to. I've got some other stuff keeping my busy at the moment but if it seems quick and easy I might be able to fit it in.
