Thanks for the link, Reda. I have not heard about app streaming before.
However, I believe that app streaming addresses a slightly different need and is applicable to another array of use cases. It is useful when you are not aware of which service can solve your problem and you search for it.
The class of use cases that Ted originally described in his post is of another nature. There you know what kind of service you want, often you even know what you want from it, so you just need a convenient and familiar interface at the tip of your fingers with minimum overhead.
