No but theoretical round-trip times are getting pretty dang short as these sats are launched into lower and lower orbits. The round-trip speed of light to a geosync orbit is 239ms, but some of these LEO sats are already sitting as close as a 4ms round-trip away, and there have been proposals for some even closer.
