METAbolt is an open source (fully accessible using JAWS) messenger type application (text client) for the metaverse (virtual worlds). It has most of the functions that a viewer has but just not the graphics (excluding the feature to view individual objects and HUDs in 3D). Hence you can perform most of the tasks you are able to with a viewer.
METAbolt has been in existence for over 3 years and has a thriving user base of 200K+ people worldwide with which it is closely knitted in terms of development and direction. The METAbolt user community is the main driving factor behind the project. The METAbolt project is very active in the sense that improvements are made and new features are added on a regular basis.
