This paper describes the eBag infrastructure, which is a generic infrastructure inspired from work with school children who could bene t from a electronic schoolbag for collaborative handling of their digital material. The eBag infrastructure is written on top of the Context-aware HyCon framework and collaborative web services based on WebDAV. A ubiquitous login mechanism has been built based on BlueTooth sensor networks. The eBag infrastructure has been tried out in eld tests with school kids. In this paper we discuss experiences and design issues for ubiquitous Web integration in interactive school environments with multiple interactive whiteboards and workstations. This includes proposals for specialized and adaptive XLink structures for organizing school materials as well as issues in login/logout based on proximity of di erent display surfaces.
