Technology Coach: An Idea who's time has come?

With the rise of the "professional career coaching" industry over the past few years I've begun to wonder if there is a market for "professional tech coaches".

Virtual training classes, and the associated cost savings, have allowed TrainingCity to successfully "lower the bar" on our minimum number of class attendees. What if we could lower the bar to one?

Imagine being able to attend a "training class" where you were the only student. A kind of "fully customized", but live and interactive, training class. Of course this is always an option if you have the $$$$$, but what if we could find a way to create an environment where you are able to interact one on one with a single TrainingCity instructor in a full duplex, real time environment for the full duration of yor training class?

If TrainingCity could find a way to "optimize" the delivery of live virtual classes such that we could have several attendees interacting with the course content, online labs, background materials, workshops, break out sessions, etc, in a slightly time staggered process, it might be possible to "optimize" the flow of students through a set of course objectives such that they each get the impression that they are experiencing "one on one" training (coaching?), a kind of "Time Division Multiplexing" of the instructor!
