The Space Frontier Society has some ideas. I agree with most of them.

It's hard to see them being implemented, though. I don't even see a serious policy debate going on right now, despite all the noise about the Columbia Accident Investigation Board.

The Space Frontier's "New Space Policy" is great.

Sadly to state the obvious, the political climate is inevitably hostile to the development of cheap RLVs as follows:

1. A large industry has developed that is dependant on (a)expensive ELVs and (b) the expensive shuttle system.

2. Nascent develoment of cheap RLV systems by private companies e.g. Kistler, Scaled Composites (Tier 1) etc directly threaten thousands of jobs and hence a huge and powerful political constituency.

3. Expect intense pressure from NASA/ ELV companies/politicians to block any test flight of any hardware that threatens the status quo - hence (a) inability of Kistler to realise funds for test flight of K1 vehicle (b) regulatory hurdles in way of suborbital test flights of e.g. Spaceship 1 (c)were Northrop to succeed in increasing their minority holding in Scaled Composites to a majority holding, expect a subsequent abandonment of Tier 1 or its follow-on as being "impracticable".
