Cubase has had System Link for a long long time. I’m not sure if Node or Link was around first. I actually had a 3 computer System Link setup for a couple of years. It worked pretty good. But managing 3 boxes is just too big a PITA to put up with (not to mention heat/noise), when current comps are so kick ass powerful.
And, just like the Logic Node, for every person who finally manages to get it to work well, there are 200 people who can’t keep it running and finally give up. It is such a fringe group of users, that I doubt either company will spend a lot of muscle worrying about.
