We are interested in integrating and exploiting the sharedknowledge from a group by an existing infrastructure of plasticity, as another parameter more to be embedded in the adaptation process. The aim is to offer the benefits from plasticity and awareness jointly, providing a systematic support in both issues. In this paper we focus on the proactive adaptation to contexts of use under a plasticity viewpoint. The aim is to promote interaction and real time coordination, contributing to real collaboration in multiple and changing groupware scenarios.
