After the launch of the Mobile Web Initiative at the World Wide Web Conference 2005, awareness is emerging that, today, mobile Web access suffers from interoperability and usability problems that make the Web difficult to use. With the move to small screen size, low bandwidth, and different operating modalities, technology is in effect simulating the sensory and cognitive impairments experienced by dis- abled users within the wider population of mobile device users. The Third International Cross-Disciplinary Work- shop on Web Accessibility (W4A 2006) was targeted to bring together different communities working on similar problems to share ideas, discuss overlaps, and make the fledging mobile Web community aware of accessibility work that may have been overlooked. The main question asked was: ''Is engineering, designing, and building for the Mobile Web just a rehash of the same old Web accessibility problems?'' This lead to addressing issues such as: • Are the same solutions required for the Mobile Web and for accessibility and can the two communities work together to solve these problems? • What can the Mobile Web learn from the Accessible Web and what resources created to support the Accessible Web can be used by designers in their support of the Mobile Web? • To cross-pollinate do we need to rethink the current view of accessibility? Therefore, the workshop brought together a cross section of designers, engineers, and practitioners working on both the Accessible and Mobile Webs; to report on develop- ments, discuss the issues, and suggest cross-pollinated
