Can Light Speed Exceed 'c' in Alternative Physics Theories?

[member 11137]

I beg my pardon in advance for the stupidity of my question.

Is there any "Behind the standard model" paper, document, crazzy theory, essay... exploring a universe where the speed of the light would have several upper limit: c, 2c, 3c, ... N. c? (with c = 3. 10⁸ meter/second)

That is.
