TDR functionality requires analysis capability (software), and very accurate pulse generation / measurement ability (hardware). It's not something that can just be added to PSDR; there would need to be hardware in the 1500/3000/5000 to support this and I doubt that it's in there.
And as far as developing this into the 6000 series...I would rather Flex worked on making them the best possible transceivers first and foremost. An AIM-4170 can be bought for about 1/10th of the (proposed) cost of a 6700.
