Not to be a killjoy about that technology, but if there is any way to play it back in full res, even just once, the hack around the copy protection is easy.
Play it, just use TotalRecorder (or another of several softwares) to record it "live," and you've ripped it.
Frankly we used to do this all the time with music companies to test out different tracks before we decided which to use (and buy)... even if the files weren't downloadable (which they often weren't), we'd just play them off their websites and record them at the same time. Sounded great.
Now we are
painfully honest and never used a track without paying for it... but I always thought how easy it would be to do so for less trustworthy types.
So I don't think any kind of copy protection is nearly as secure as a watermark.
Or you can just work with clients that you trust not to screw you over.
