I don't know how normal people will use SACD with an external DAC. The physical format is pretty much locked down, and there are one or two proprietary ways of transmitting that data from a couple of players, but I can't imagine what licensing costs, never mind the engineering effort, will be like.
I do know that you can hack older PS3s (the ones that can play SACDs, unlike the latest ones), and pull the DSD data off the disk, but that seems like a really small niche to serve.
DSD is also 64x44.1 kHz single-bit stream. Unless you're using a DAC chip that can accept that kind of data, you will have to process the DSD to something else in order to convert it to analog. I'm not sure DSD's really worth the trouble.
And I agree that DSD is inherently flawed as a format. It's pretty much the dumbest thing one can do: standardize a protocol around a snapshot of a particular technology at a certain time. DSD is just the raw output of a single-bit delta-sigma ADC.
