A more practical sort of interstellar travel?

Various radio messages have been beamed toward nearby stellar systems.  I contributed to one a couple years ago.  (My contribution was a warning to anyone who got the message.  I warned of humankind's rather imperfect value system.)  But perhaps we should send the complete digital description of the human genome.  Or perhaps those of various humans.  Along with this would be an attempt to explain what the message is.  One might hope the recipients could then construct human beings at their end from atoms available there.  Perhaps spaceships aren't needed. And perhaps a larger fraction of the space budget should be spent on seti. As a hedge against global catastrophe we should begin to send such signals now.
