If I'm on the interior surface of a rotating cylinder in space, I'll feel something that I could interpret as "gravity". Is it possible to spin a cylinder fast enough to create an "event horizon" on the inside?

Basically, ignoring material constraints, is it theoretically possible to make it so that centrifugal force creates an "escape velocity" greater than C? Also, would light coming from that surface appear redshifted in some reference frames but not in others?

Basically, what's the relativistic interpretation of pseudoforces like this?

No. The "gravity" you are talking about would be caused by the accelerated circular motion of the cylinder walls. The walls would have to move faster than C  to prevent light from moving away from them, and that is impossible.

Absolutely. Why not? Any motion, even without acceleration, would produce red shifts and blue shifts.
