To answer your question about music on the web, these aren't all always folk, but they'll get you started:

Canadian (CBC) here

our own Rick Fielding's show, Acoustic Workshop can be heard Monday evening at 9pm EDT on CIUT here

there are three different stations available here, which include world music, bosnian music, and an ecletic mix at Web Radio

and this is a fantastic site for all music native American, contemporary to traditional at AIROS

I've got one more bookmarked, but haven't been to it in a while so don't know what it has. It is at Netradio Network

I know there are more for folk, but don't have them handy.

Have fun,
