I see only one problem with the whole concept of establishing remote colonies that will never exchange population (ala remote seeding ships). That problem is called Evolution. When a population of critters is cut off from the main population of critters, the two populations evolve along different path. Eventually, the splinter critters aren't critters anymore, they're creepy crawleys, or what have you.

So if HUMANS establish remote colonies in other starsystems WITHOUT the ability to travel back and forth fairly regularly, those remote colonies will eventually not even be human colonies anymore. They'd be aliens!

Evolution requires the driving external pressure for the survival of the fittest. Progress in technology excused humans from the general natural order. Even primitive Stone age technology freezed our evolution for 400K years now - there were no changes in our nature since
