There is no limit to the number of podcasts that can be created. Podcasts can be uploaded through either the front-end or administrative back-end and Administrative Workflow is very straight forward and is built based around moderating and approving user-submitted media.
MediaCore is completely W3C standards compliant and degrades gracefully for legacy platforms and screen readers. It utilizes TurboGears, MooTools, and Python.
