BeeWeeb Technologies, an Italian software-house (does anybody still use this term?), has recently launched the first version of a new software called “Mobile Web Toolkit“.
The Mobile Web Toolkit is more a technology and a set of tools rather than a simple software. The technology is the result of a few years of experience developing software for mobile devices and for mobile operators, it is a technology to produce a layout that is mobile-friendly from content that was meant for desktop browsers.
Its current incarnation, and only open-source, is a plug-in for WordPress, but BeeWeeb has promised to release more plug-ins and libraries. The open-source version is based on WURFL, but reading the FAQ I think they also mean to provide tools to carriers and that will be based on a proprietary technology that might, later, be integrated with WURFL.
I also spotted a web-version of a presentation they made on the Mobile Web Toolkit that also adds some info about the technology in general and their plans to release more software in the near future.
