absoloutely: the next step would be to harness the abilities of a) time dilation (http://spaceplace.nasa.gov/en/kids/phonedrmarc/2003_may.shtml, http://www.google.co.in/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=UrK&q=time+dilation&btnG=Search&meta=) to allow for future time travel in some space ship, and the ability to drop someone into a coma / life support device for a lifetime or more. If stuntmen, soldiers and astronauts are willing to take those risks I'm sure someone would do this.
Seriously, it won't happen in our lifetime, but who could have imagined planes realistically 200 years ago? If we are sent back pictures of a human society (but 2009 years in the future!) on another planet, it would inevitably unite the people of earth, and probably invoke an worldwide effort to make contact. Or perhaps governments to devise operation 'Enduring Intergalatic Freedom'. Eitherway, I find it credible.
PS. Pater@slashdot.org give us an option for the old slashdot back in preferences - the new ajax doesn't work in many places.
