With computers, theoretically you could fit thousands of distinct consciousnesses in a computer the size of a sugar cube. And computer consciousnesses could be "frozen" rather than put in to suspended animation for the journey. Add some nano-tech replicators and a spacecraft could be no larger than a football, shoot out across the galaxy, find a planet and start building android bodies, buildings, telecoms, a complete civilization. Even human bodies if you really want.
Again, fanciful, but more likely than sending people.
