The OpenSimulator Project is Virtual Worlds Server which can be used for creating and deploying 3D Virtual Environments.
It has been developed through an open-source model.
Out of the box, the OpenSimulator can be used to create a Second Life(tm) like environment, able to run in a standalone mode or connected to other OpenSimulator instances through built in cloud technology.
It can also easily be extended to produce more specialized 3D interactive applications.
OpenSimulator is written in C#, and can run under Mono or the Microsoft .NET runtimes.
Due to its clean modular nature it is possible to significantly extend functionality yourself via plug-in modules to suit your application.
OpenSimulator is currently considered to be alpha level code (please refer to AI 27).
OpenSimulator is working with Linden Labs on Virtual World interoperability.
