Someone in the other forum said:

"One of Arlo Rose's early claims to fame, long before Konfabulator, was an extension to Mac OS 7.x called "Aaron". What Aaron did was copy the default Copland interface (aka 'Platinum') from the then-planned Mac OS 8. It was a straight up copy."

This does put things in a new perspective. Arlo Rose is in no position to argue if he's done the copying before.
