These seem like large technical challenges, but relatively minor changes in
our economic models and assumptions. Externalities and public goods are
familiar issues, though the details may change.
I worked on systems which allow barter among scientific experiments on
spacecraft, and so I know that there do tend to be more externalities among
nearby systems, at least on the small scale. These include vibration,
pressure failures, and radiation shielding. But the costs of monitoring
such externalities should be very low, and we are already used to having
lots of substantial externalities among humans on small space scales.
Having a viable space colony economy is very challenging, mainly because
that economy has to be very self-sufficient in all physical goods. I think
this is why we won't see such colonies for a long time to come. (I say a
bit more on this at http://hanson.gmu.edu/dreamautarky.html )
