Then good news! After the Star trek reboot, warp drive will no longer be necessary! In the first movie, we saw a successful transport to a ship in warp. Warp drive moves a ship nice and fast when it's working, so that's a huge range increase. In the second film we saw a transport from Earth to Kronos. Warp is out, transporters are in. The only ships that will be required in the future will be the ones that construct new (small) starbases to receive and re-transport people to any destination that is out of range. These stepping stone stations might fit in something less than the size of a small shuttle if they can simply retransmit the pattern from the transport buffer without rematerializing it.
