"If Rand Simberg is right, the next year may see the equivalent of the Cambrian explosion but in space access by many nations. I for one would like to see other nations involved."

I agree. Free trade. How are we going to have sub-orbital travel if we try to stop other nations? But some people are going to go bananas [dare I say "ballistic":], so we will need some compromising, at least until the time people see it's not as dangerous as they might imagine. And also it's very unlikely that there will be some "serious flap" connected to this, so, with the proper restrictions in place, after this happens it will be like not going grocery shopping when hungry.
