3Di Viewer "Rei" is a browser-based 3Di virtual world viewer that can connect to Opensimulator or 3Di OpenSim servers. "Rei" is an almost complete rewrite of the open-source IdealistViewer and adds support for mesh display, group and private voice chat, avatars (with 3Di OpenSim). This is a Windows-only software and supports Internet Explorer and Mozilla Firefox.

Development on "Rei" stopped early 2010, although at the time features were still being developped for the closed-source 3Di OpenViewer (which has also been discontinued since)

I created the plugin system in "Rei" where the vision was that we would facilitate a kind of marketplace for virtual world viewer plugins by third parties. In the end only two plugins were created: a voice chat addon that has not been released as open-source and the Wiimote plugin, which allows players to control the avatar with a Wiimote.

This plugin has been demonstrated at the 3Di booth at CEATEC.

SLVoice is an open-source replacement for the vivox voice chat addon in SecondLife. It supports group and private voice chat for OpenSimulator and Asterisk or FreeSWITCH. Open-source development of this software has mostly stopped by late 2009, when at 3Di we moved toward better performing, but unfortunately proprietary PBX and RTP client solutions, so SLVoice is only compatible with the SecondLife Viewer up to version 1.22

Immersive Seminar is a web-based conferencing and virtual seminar application based on 3Di OpenSim and 3Di OpenViewer. Besides the domestic offering I have proposed and (with a team of only two) implemented a global offering that was a cloud-based on-demand service. Sadly the company was just going through a transition away from OpenSim so the the global offering never got out of beta.
