To be honest.. I have wondered wether this is the direction the Hackintosh may go now Intel is out the window. I guess only time will tell.
As of how MacOS would actually run on the iPP, I think it would actually be okay for light use. You can actually install and run MacOS with only 4GB RAM. I think the biggest thing would be thermal headroom on the iPP.
I believe its only inevitable that someone somewhere out there will get it to run though.
