I found this idea interesting because there are so many projects where I'd like to receive a text message indicating something timed out or a process completed. That way I don't have to sit and monitor it or check back often. One such process is 3D prints. When a print is done I'd like to receive a text message letting me know.
The module relies on an internet service called IFTTT which stands for If That Then This. I've visited the site and it appears to be some kind of scripting language setup that allows you to easily create actions based on various inputs and outputs all connected through the internet. I hope to understand it a lot better when I get the CLOUDBIT running on my Davinci 3D printer so stay tuned if you have any interest in this type of project.
