Wader is a 3G device manager daemon written in Python and tested on Linux and MacOS X (10.5 with recent MacPorts).
Some of its features are:
Warp Networks developed Vodafone Mobile Connect Card driver for Linux for Vodafone Spain R&D between late 2006 and early 2008.
When the project ended, we realized that there were some parts of the application, like the core, that were pretty good and potentially useful for other applications of the Linux/Unix desktop ecosystem that wanted to interact with 3G devices.
So Warp decided to fork it, rewrite some dodgy spots and export all its juicy bits over DBus, which was the missing piece in order to be able to talk with other applications of the Linux desktop. The project needed a new name and we chose Wader for it.
