EMC's GDDR is a bit different from GDPS. Right now EMC's product, SRDF, is a 
DASD controller to DASD controller based operation. The controllers are 
commanded from EMC's Host software running in an LPAR. You control the DR 
controller from the host system. People asked for a way to control the DR 
controller from the DR site. EMC's solution is to have you run a z/OS LPAR at 
the DR site which runs EMC's Host software component. Then you somehow 
get access to z/OS in the DR site and do commanding locally. So GDDR gives 
you the facility to do all this. 

The advantage of the DASD controller to DASD controller operations is the 
lack software licensing fees. Running GDDR would mean paying EMC for the 
remote Host software not to mention IBM for the z/OS software of the LPAR. 
My question to EMC is could it be z/OSe or its follow-on which I think is eWLC 
pricing. Then we have the ISV's who will most certainly claim you are running 
images at the DR site and want you to license all their products because they 
are installed on the machine and you are running z/OS all the time. Last time I 
checked all the majors and many minors, they want money.

The implication from EMC is GDDR was meant for SRDF. I never asked about 
PPRC.
