Using previous experiences of designing elearning systems, we have started a new project, Ubi- Learn, which aims to support the remote learners in various situations, mobile or fixed. This means a great variety of communication channels such as Web, email, SMS, phone call This leads us to consider a large range of scenarios of use, where channels are combined in a same unit of interaction depending of the context. In the context we capture not only information about the technological and physical contexts of interaction, but also the user profile, and the nature of the activity and its history. Ubi-Learn intermediation is based on the assumption that the learning system is factorised into a collection of dedicated e-Services, and that the user interactions with the channels can be abstracted with a channel independent modelling language. The management of these intermediations is achieved through a multiagents infrastructure combining several sources of contextual knowledge, especially for the dynamic orchestration of the e-Services.
