Hopefully one of the controllers will chime in here and tell us what the
proceedure is if an unidentified aircraft is detected approaching the US
above FL600. It is probably greeted with a missle.

Nothing that I have seen or you have posted says that "international
airspace" begins at FL600 and anybody is free to overfly anywhere above this
altitude.

A practical definition of "space" is the lowest altitude where objects can
orbit which is around 100km.

What document and organization put forth this number? What nations have
agreed to it? What happens if a non-signator violates it? What court
has
jurisdiction?

I think space begins by agreement at 100km or something like that.

No, the ABC airspace only goes up to FL600 but that does not imply
that
the
underlying country does not own and control airspace above FL600.
Airspace
above FL600 is class E airspace in the US. Try flying over China
above
FL600 or ask Gary Powers if you want more.

Where do satellites fit into this definition?

Or, rather, where does international outer space begin?
