I guess the difference is that this guy is making the recipe available so you can tweak it to your requirements.
Ensure or other prepackaged products are a predefined set ratio, which may not be optimal for all consumers.
For example, highly active people will probably require a higher ratio of carbohydrates than less active people. Similarly, some people will be genetically predisposed to have higher/lower uptake of some nutrients/vitamins.
Ultimately, for any one person to succeed with a Soylent style approach, they will need to monitor their blood levels of a range of elements and compounds.
To my mind, developing a rapid, cheap, broad spectrum blood analysis to allow people to monitor their diet (soylent or not) is what should be focused on.
