Momentum feedback from super-Eddington accretion offers a simple explanationfor the observed M-sigma and M-M_{spheroid} relations between supermassiveblack holes (SMBH) and the spheroids of their host galaxies. Recently Ferrareseet al. and Wehner & Harris observed analogous relations between the masses ofcentral star clusters and their hosts. We show that stellar winds andsupernovae from such nuclear clusters (NC) give similar feedback explanationsfor this case also, and we discuss the connection to the Faber-Jackson relationfor the spheroids themselves.Comment: Added reference to J.
