Wow, pretty cool to hear Peter Bernard mention smartFeed.  He's pretty much on the money... smartFeed is a podcatcher for the MS Mobile platform.  It's built on top of the .NET Compact Framework and it's available for free (absolutely no strings attached).  Kevin and I have sunk a lot of hours into this baby and we'll continue to do so because we use it every day.  smartFeed is by far the most exciting project we've got going on right now.  Please check it out and let us know what you think.  You can get it at http://www.smartfeed.org/download.aspx.  I know this is kind of a shameless plug, but I just spent our entire marketing budget on my daily cup of coffee and now I have to take advantage of every opportunity I get =)
