Scram Success

So you've all probably read that the latest Mach10 flight was
successful. The statements from NASA's O'Keefe seem to indicate that
this technology will be used to advance commercial flight, as well as
cheaper access to space.

So in light of these post-Nov16 statements from NASA, will there be a
future for scram?

Some of you have said it's easier to get into space with a rocket, but
some of the news coverage I was reading said scram could at least be
used for a lower-stage booster.

Could scram be suitable for heavy payloads in particular?
