Could the Enterprise beam a Vampire into a home it wasn't invited into? (Assuming coordinates have been locked) Overload the transporters? Destroy the Vampire? Create something like a Tom Riker? Many possibilities, I'm interested in the answer.
Well, let's see. In the Buffyverse an vamp seems to encounter an invisble wall when trying to enter uninvited. Maybe the transport would simply fail as if encountering a force field. IF technology is at all affected by the supernatural, and vice/versa.
