This American Life Asking for Donations to Cover Bandwidth Costs

This American Life says it's spending $130,000 annually on bandwidth for its podcast. Why isn't a popular show like this using Bit Torrent?

Miro, the open source torrent player, makes downloading This American Life quite easy. It's also quite easy to use. 

I installed Miro and downloaded the latest show #1 Party School via BitTorrent in less than two minutes.

Am I missing something or could the show save a ton of money by encouraging people to use a BitTorrent downloader? I love the show but should donors pour good money after bad uses of bandwidth?

Perhaps the show could create a custom download of Miro (it's open source) that installs with an automatic subscription to This American Life?

Has big Internet (Comcast, et al.) sewn the seeds (no pun intended) for fear of BitTorrent and discouraged innovation? e.g. Why doesn't iTunes use BitTorrent?
