If my math is right geostationary satellites have a round-trip time (just at speed of light in a vacuum) of ~240 mS whie LEO satellites have a round-trip time of ~13 mS.
Current observed latency on geostationary satellite uplinks is 550 mS, presuming delays scale linearly with the travel time in vacuum that puts us at ~30 mS round-trip for LEO satellites.
Sub-100 mS seems physically possible to me but from an engineering and volume perspective there may be a real challenge.

Anyone with more knowledge care to chime in?
