The usual warnings apply about large data download over cellular networks because of the potential for high costs (if you are not on an unlimited data plan). However the N91 and other S60 3rd Edition phones (N80, E60, E61, E70) include WiFi which is probably the best option to use when downloading large data files such as podcasts.
Nokia have stated that future plans for the Podcasting application include the ability to not only listen to podcasts, but also to create podcasts .
