I've tried it. I found it difficult to mix into without compressing it too much. I like the concept a lot, and I will look into it further in the future, but I think it's quite tricky to do it well. It's very easy to go overboard. At least that's what I found, but maybe I just need to practice it more.
As for DAW vs analogue, aside from the comps sounding/acting differently, I can see how it could be a problem as latency compensation fixes everything these days... I need to study it again. I think it was some weird routing he does that is hard to replicate in DAWs maybe?
