As a person who is trying to patch (a now rather old version) of OpenSim to handle voxel terrain, there's MANY, MANY flaws to the messaging subsystem of both the viewer and the server.
For one, I wanted to tack on an additional UDP/TCP message to handle voxelmap transmissions and modification. Unfortunately, it appears that even a tiny change to the messaging template would completely destroy compatibility with SL, and even adding one packet handler in OpenSim would involve changing LibOMV, 3 packet handling packages, and an extremely long PacketType enum. This is NOT a flexible protocol that we're using. In order to retain compatibility with "legacy" viewers that only support heightmap terrains, I'm having to add in additional capabilities to OpenSim and the viewer, which I don't like, as HTTP transports are going to be godawfully slow, particularly when adding, removing or modifying voxels.
