Depending on the type of event and how immune you are to being embarassed, creating a mobile sound clip with decent sound quality can be difficult. Recording a concert event, for example, might be easy because people expect it to be loud and racous and have all sorts of ambient noise. Mobilecasting a presentation, however, engenders hopes of much higher quality.
Good gear, however, can cover up most sins and if you're willing to spend enough money on directional microphones and killer windscreens, then you can produce a pretty decent podcast.
