Hitching a lift on somebody else's commercial launch or paying
commercial rates makes it possible now, as I understand it, and
somebody on Sunday mentioned that there were amateur groups working on
400,000 ft altitude rockets there, which is technically space as well.

That's harder ;) Sub-orbital is probably achievable for Spacebridge.
LEO requires a *whole* lot more energy; geosync requires even more
energy plus dealing with a much, much nastier environment. Probably
not in the next 3 months, I'm thinking.
