Podcasting server specs

Question: What specifications do you recommend for a district podcasting server?

The IT Guy says:
Podcasts are generally just mp3 files that are hosted for standard http download by Web browsers or podcatching software programs like iTunes or Juice Receiver. Specifications for a podcasting server are really not any different from what you would want for a standard Webserver that is going to receive a large amount of traffic.

When a new podcast is published, all users subscribed to that podcast feed will request download of the latest episode the next time their podcatching software runs. For podcasting, a high end server with as much Internet bandwidth as possible is desirable. To reduce the load on the server for extremely popular podcast channels, consider throttling the maximum throughput for downloads to individual users down to something like 20 kbps.
