I use subsonic (subsonic.org). It's cross platform (linux, windows, mac, android, ios, anything with a web browser and flash) and supports auto podcast downloading. You can also use it for video. The only caveat is that it doesn't sync to an ipod. There are multiple desktop clients to choose from and I haven't seen one yet that will sync to an ipod. If you have an ipod touch you could use one of several different apps.

From Adobe's Security Bulletin Affected software versions Adobe Flash Player 11.5.502.146 and earlier versions for Windows and Macintosh Adobe Flash Player 11.2.202.261 and earlier versions for Linux Adobe Flash Player 11.1.115.36 and earlier versions for Android 4.x Adobe Flash Player 11.1.111.31 and earlier versions for Android 3.x and 2.x If you're running on Android it might not show in the market but if you view "All Apps" which shows previously installed apps along with ones currently installed, Flash will be there and say Update next to it. I think it's also interested that this comes about a week since Firefox started blocking all plug-ins by default, except Flash.
