Podcast Possibilities (OR If I had more time...)

In our ideal library world the possiblities for using this kind of technology are many.

I could also see us recording special events, recording monthly newsletters, creating training podcasts . I wonder how easy it is to do. It looks like it should be fairly straight forward...
