"<The problem is how do you lower launch costs "by a factor of 10 or higher".
You seem to be think the solution is to develop scramjet technology and build launcher which uses this technology.

let me stop you right there. Thats a connection YOU made, not me. I could care less how they do it as long it it means CATS."

Well, that's why I used the word "seem" (and grammatically, I should have wrote "you seem to be thinking..." [or you seem to think]).
Anyways I guess, you are saying scramjets may or may not be neccessary.
The next point is who do you mean by "... they do it..."?

"scramjet is just something I woudl like to see."
I would be also happy, even if someone could prove it worked to any extent.

"Furthermore I think you pessimistic view of the government developing CATS is heavily influenced by NASAs poor performance as of yet. I suggest we wait until its administration is overhauled and then give it a chance."

I see no reason to expect such miracles from the new administer- I do have high hopes but I'm not expecting that he will be able to walk on water. NASA is simply incapable of "delivering"/developing CATS. NASA can certainly do things which might lead the private sector in this direction. And I do expect the new administer to do that.
