The ability to cheaply simulate environments is at the core of many VR education/training concepts. I hadn't heard of it being applied to language education, that's really interesting! Second Life specifically excels at being a platform for roleplaying (in the educational sense as well as the D&D sense). The built-in creation tools allow people to very quickly create environments that have enough fidelity to be a significant step up from 'this table is now an airplane' and thanks to the marketplace one can often quickly and cheaply acquire ready-made props for virtually any scenario. Using the more advanced creation tools one can even create video-game-level fidelity however that is usually not necessary for educational environments.
