Patenting Podcasts

What does it mean that VoloMedia's been granted a patent for the process of podcasting?

It's explained by Marketplace's Jill Barshay here.

It's interesting reading, but here's one of the key quotes by VoloMedia's founders, Murgesh Navar:

I can tell you categorically we are not trying to stop anybody from creating a podcast or distributing a podcast.

Some are wary, however. I don't think it'll affect an end user like me, but I sure hope it doesn't scare off any of the podcasters I love.
