Just released an initial beta of my pod catcher app, Poca.
Poca is a windows service app that runs in the background downloading sutup pod casts. I has a desktop app that allows you to manage the service.
A couple of years ago released a add-in version for Windows Home Server v.1, but his version is not an add-in, but is compatible with Windows Home Server 2011, Windows 7 or any other Windows desktop or server versions since the introduction of Windows XP. The app is 32bit, but I have tested it under 64 bit Windows 7 and Windows Home Server 2011.
