Rocketplane XP - what's the TPS?

Any know how they are going to do Thermal Protection for the
Rocketplane XP?
Surely a stock Leer Jet fusalage will melt on reentry from 100KM, right?

If it's doing a SpaceShip One-type trajectory, it won't need much in the way
of thermal protection. Remember that the speed of reentry is going to be
low; it's not like an orbital reentry.

The TPS on the X-15 was AFAIK more for the high-speed research flights, not
the high-altitude ones.
