Key point:
Quote :
affordable unmanned scientific missions to low-Earth orbit
IOW, no geosynchronous satellites, no manned travel, no extra-planetary. How many "developing" nations could (or would) afford their own LEO satellites instead of leasing space on the already-overbuilt existing satellite networks?

I'm missing your point. The whole idea is that they don't need a satellite. The experiments go up in Dream Chaser. It orbits for a while, as work gets done. And then it comes back, bringing both the results and the experimental equipment home again.

Good point.  LEO satellites aren't the only task a shuttle can accomplish.  Long-term scientific experiments can take place on the ISS -- not on a shuttle --

Will the Dream Chaser be authorized to supply the ISS?

The Dream Chaser is designed to resupply the International Space Station with both pressurized and unpressurized cargo.
Yes, I guess it will.

Nevertheless, private-but-still-outrageously-expensive access to the ISS will hardly "transform humanity's access to space."

The Dream Chaser is pursuing the same market as Elon Musk's SpaceX.

According to the book I just read, NASA used to bill something like $600 million to place a satellite in orbit. The Russian space agency will do it for $300 million. SpaceX aims to do it for a little over $20 million.

What will Dream Chaser charge?

Dream Chaser isn't about putting satellites into orbit. And the dream part isn't about supplying the ISS either.

The Dream Chaser showed up in the deleted scenes of "The Martian." It was credited as such.
