I'm currently working on https://keepallthethings.com which offers a similar service only web based with a GUI so it will either be more useful or less for you depending on your use case. If anyone wants to try it out go through the sign up process until you hit the credit card form and stop then send me an email(in my profile) and I'll set you up with a free account. Its just launched so there are a lot of features still on the roadmap instead of implemented but it'd be nice to have other peoples feed back/ideas for improvements as I go.
