We develop an extensive set of inequalities which apply to the surface of a relativistically rotating fluid with asymptotically flat exterior. We explore the physical content of these inequalities by examining the restrictions they impose on the existence of rotating fluid models with Kerr exteriors. In that case, the dominant set of inequalities can be expressed in a simple analytic form. We find for all models with Kerr parameter a>m that there is a finite maximum redshift between observers at the fluid surface and at infinity. However, for all models with 0..0, a finite redshift maximum emerges in a discontinuous manner. The value of this maximum depends upon the moment of inertia of the static background fluid. We discuss the implications toward the possibility of a high redshift quasar model.
