The long term goal of the project is to create a way to archive TV shows off of your Tivo and provide a mechanism to transfer the shows back on demand for showing. I'm working on creating it on Python, and as a starting point I've begun work on a general python library for interacting with them. Right now provided an IP address and your media access code it can connect to your tivo and give you a listing of all of your shows.
My eventual goal is to provide it both a web interface and an interface that the Tivo can use as well as add autodiscovery of tivo devices. I'd like to also tie it into pytivo for the show playback. One nice thing is that would allow you to compress the shows for better storage.
If anyone is interested in taking a look I'm hosting it at Sourceforge as a way to do revision control as well as learn Subversion a bit better (I'm more familiar with Perforce right now).
