We report on preliminary numerical MHD simulations of magnetic disk accretion surrounding a compact protostar in which the disk and the hydromagnetic wind interact self-consistently. We show that an outflow is indeed produced, but that its properties are sensitive to the assumed initial poloidal magnetic field structure. In particular, we reconcile the apparently disparate models of Pudritz and Norman (1983,1986) and Uchida and Shibata (1985) concerning the mass ejection mechanism.
