Of course, you clearly wouldn’t attempt such a voyage until the technology to revive the crew (and done totally automated, at that), probably using suspension techniques even better than today’s, also existed and was well demonstrated…

And indeed, I might expect that ability and the capacity for limited interstellar travel, to occur at roughly the same time.

Future revival will be contingent upon technology
that can cure all diseases, rejuvenate people to
a youthful condition and repair injuries caused by
the cryopreservation process. Diseases are not
magic, they are mechanical damage caused by
damaging agents of various kinds. If damage due
to disease and aging can be repaired on the molecular
level, then damage due to cryoprotectant toxicity
and even freezing could potentially be repaired.
Stem cells very probably will be useful in
replacement of organs and tissues that cannot
be repaired on the macromolecular level.

A detailed explanation of the science
behind cryonics procedures can be found at:

http://www.cryonics.org/reports/Scientific_Justification.pdf

You cite a paper which calculates the probability
of cryonics working as being no better than 15%. But in
the appendix of that paper another scientist calculates
the probability of success to be between 13 and 77% –
probabilities more in line with the estimates of
most cryonicists.

The Cryonics Institute offers whole body cryopreservation
(including vitrification perfusion to prevent ice formation
in the brain) for as little as $28,000. As a matter of
policy, CI does not offer a neurocryopreservation service,
unlike Alcor.

Anyone interested in more than the superficial, dismissive
coverage of cryonics that you present should read the
Wikipedia entry on cryonics, or Google “cryonics faq”
to get answers to the most Frequently Asked Questions
on the subject.
