Introduction

While there is no standard Virtual World protocol that will insulate us from the details of a particular implementation, there is an existing open source project that comes closest to fitting our goals.

OpenSimulator began life as a reverse engineered copy of the Second Life server, implemented in C#. However over time it has evolved into a 3D application server with a choice virtual world protocols. OpenSimlator is liberally licensed, modularly designed, and boasts a large and active open-source community.

For our real-time protocol, we have chosen to use a modified version of the SLUDP, due to Second Life's evident popularity, maturity, and large userbase. The extreme modularity of the OpenSim codebase makes this extension, called ModreX, simple and clean.
