Pretty much this. I've been drinking a concoction of Spirulina, Hemp fiber+protein, Rice milk, and MCT oil, for a couple of months now, and not only is it cheaper than most commercial MRPs (including soylent), I've found it to be much more satisfying and about as nutritious as well. That being said, I haven't exactly ever tried to live off any MRP for any prolonged period of time, which I guess is the 'novel' claim this product is being pitched under. At least they seem to be open-sourcing the recipe and keeping it relatively simple (as far as MRPs go).
