The Wockets project consists of both hardware and software development. You can critique the design specs for either.
Hardware for real-time acceleration measurement
To find details on the Wockets hardware design, see the wiki hardware design pages. You can also send ideas or critiques based on the information on the wiki to the developer's mailing list.
Software for detecting physical activity
To get details on the Wockets firmware and phone software, we are using with Wockets Google Code site. Now that our hardware design has stabilized, we are in the process of cleaining this site up so that it is easier for developers to get started developing for Wockets.
