I have some Python projects in states of reasonable completeness. I have a (slightly fevered) dream of writing my own simple and easy-to-use smtp server some day.
Poca is a command line podcast client, written in Python. I started it way back in 2010 as a simple learning project script, but it grew to be a solid, capable and easy-to-use podcast tool. It leaves extensive options in the hands of the user, including id3 tagging, cronjob compatibility, error logging prefs, filters, etc.
