In this paper is illustrated the development of FireFly, a system for the Face to Face Collaborative Learning (F2F-CL). FireFly is written using AJAX, a set of technologies that allows to create rich web-based application. The challenge is to develop a system able to be executed on usual desktop PC, requesting the lesser possible installation effort and achieving enough expandability to allow further extensions. The system is currently under development, but the prototypes and the early tests confirms that the use of AJAX technology for this kind of application is suitable and deserves further investigations.
