Virtual Worlds may become primary tools for learning many aspects of history, for acquiring new skills, for job assessment, and for many of our most cost-effective and productive forms of collaboration (Metaverse Roadmap Report, 2007). We will present some non-intrusive and dynamic e-learning based scenarios related to multilin- gual textual information within an immersive 3D environment. We refer to these scenarios as non-intrusive because they do not interrupt the user's activities within the immersive 3D en- vironment. Rather, they enrich his/her individual experience. Obviously, these scenarios need to be dynamic, because user interaction occurs mostly in real-time. In addition, these non- intrusive and dynamic e-learning-oriented scenarios exemplify how a standardized framework for textual multilingual support associated with an immersive 3D environment, may consid- erably change the way people usually deal with multilingual information and with language learning on the Internet. We would like to illustrate that, in the context of immersive 3D envi- ronments, dealing with multilinguality is more than just localization and real-time automatic translations. Finally, the analysis of these non-intrusive and dynamic e-learning based scenarios lead us to propose a general architecture allowing immersive 3D environments to deal with multilinguality in the most general and dynamic way possible.
