I am not the expert at podcasts but I subscribe to podcasts through iTunes mostly because it builds the playlists and integrated so well with the ipod. So I would think the building of playlists would be an important feature. Also keeping track of podcasts as listened to or not. as with RSS being read or not is important.

Something to add to your list maybe, is the archiving of RSS and/or podcasts. Mainly rss though. I tend to keep the rticles for a ong time building a repository, this ultimately slows down the clients. So perhaps building the archive database like outlook does? Just a though. Keep up the good work.

I have written my own rss reader (www.feedisgood.com) which i dont really have time to update so would be happy to upgrade to some other software. However I cant find any rss reader that does what i want with podcasts.

- Schedule downloads. Some I want to download immediately, others can download at night for me to listen to the next day. see www.feedisgood.com/images/podcastsettings.png.

- A podcast inbox. When a podcast is downloaded it should be added to the inbox so i can see all my downloads that i have not yet listened to in one place. I dont want to trawl through through my hundreds of feed folders to find the podcasts. See www.feedisgood.com/images/podcast.png.

- I dont listen to podcasts on iPod but on PC so i want to be able to click on a podcast in the Podcast Inbox and listen to it in the inbuilt media player or an external one i have specificed.

- Another totally unrelated thing, i dont want to have to go through all folders to find unread rss feeds. I want to be able to click on the Inbox where they are all shown together and I can scroll through them all quickly. see www.feedisgood.com/images/inbox.png.

BitTorrent support would be cool ... perhaps using BTSharp:

In an ideal world plugin support for integration with 3rd party apps like media players and/or downloaders would be preferrable to specific support. Keep RSSB lean and mean in handling the feeds, let everyone else develop such extensions, that is why Firefox is so popular amongst the geeks afterall.

RSSB supports plugins according to the oneNote extension, perhaps some documentation for us novice developers?

On the issue of favicons, thanks for the screenshot. Its clarified what I thought, that they're generally to small to add any significant meaning.

Also, they kind of ruin the democratic nature of feeds. When reading current affairs news feeds, all feeds have a simple icon, title and description, levelling the field so all feeds are equally important.

Perhaps the feedicon can be viewed in the rendered feeds in the XSLT, they may look less intrusive there.

I do of course recognise the fact I appear to contradict myself with that last paragraph.

For pod/vodcasts you might want to give Democracy player a go. http://getdemocracy.com

I have been using DrizzleCast and love it because it uses BITS to download the feed enclosures making it bandwidth and performance friendly. http://www.nuparadigm.com/Products/Toys/DrizzleCast/.

While I have not used it yet, InfoCenter looks interesting. http://www.marcmercuri.com/ and might give you some ideas.

Not sure if there is any interest in the Windows RSS Platform for handling the feeds but it also uses BITS for enclosures if I understand it correctly. http://blogs.msdn.com/rssteam/
