Well the most anonymous way to acquire an anonymous cryptocurrency would be solo mining via Tor.  I'd imagine the network has quite a few large solo-miners.  Maybe someone could start watching the block explorer for the IP address associated with new blocks.  Then seeing if the IP addresses correspond with Tor public gateways.  Or if the IP addresses associated with new blocks can be linked to anywhere else.  The dev's did say they were planning on soon changing from Scrypt to a three of five auxPoW chains myriad.  While meeh did say he'd have an important announcement for us soon.
