Is there anyway to launch/listen to podcast vis the RSS reader? Can it stream versus downloading? Will it work over upnp/cifs?

I'm trying to listen to podcasts that I download (via bashpodder) to my central media server. The N800 sees the files via UPNP but I get no descriptions or dates or anything. I'm thinking of publishing a local RSS feed on that server but would like a way to stream them. I would also like a way to queue them up? Is this even possible with the N800?
