We find that a soliton solution is applicable in a fully non-linear, coronal MHD environment, and the compressive component of this solution results in a pulse wave similar to the large-scale coronal propagating wavefronts (``EIT waves'') observed by the SOHO-EIT and TRACE telescopes. Properties of EIT wave waves that have previously appeared incongruous using plane-wave theory are resolved in the context of the soliton solution. Specifically, we show: why the observed wave speed can be expected to be less than the local Alfvén speed, how a wave pulse can instigate loop oscillations, and how a single pulse can be channeled to propagate through the lower corona. We also discuss the nature of likely triggers, and find that coronal mass ejections are an ideal wave instigator.
