It was rather forcefully bolted on fgfs. The binary blobs were horrible, and the whole thing didn't really work well. But this was neither Harris' fault, nor the one's who kind-of adapted it for fgfs. It wasn't really meant to be perfect at that time. And it's also not removed, but still in CVS.

[Flightgear-devel] Addition of true comms in multiplayer
Hi people, I intend to add a module to flight gear that enables people on a multi-player game to talk to each other (live) when tuned to the same frequency on their comms. The idea is to use voip to do the connection and maybe have one of the computer's running a voip server of sorts that can handle a conference call. Has anyone tried anything similar? I would appreciate all the help I can get especially with the flightgear code. I'm exellent with C, good with C++ and elementary with xml. I have nearly no simulation knowledge but have working knowledge of dsp (digital signal processing). Hope to hear from you. Nick - This SF.net email is sponsored by: Splunk Inc.

Re: [Flightgear-devel] Addition of true comms in multiplayer
Hi, How can I get in touch with Thomas Förster. I've been told by Helko he is trying to do the same thing that I want to do.

Re: [Flightgear-devel] Addition of true comms in multiplayer
Hi Nick, http://squonk.abacab.org/dokuwiki/fgcom here you'll find the webpage for FGCOM, the project for real voice over IP in FG. I don't know if it is Thomas Forster behind this, but it is the only one project I know about voice communication. Hope this helps Seb Nick Othieno a écrit : Hi, How can I get in touch with Thomas Förster. I've been told by Helko he is trying to do the same thing that I want to do.

Hi Sébastien, Thanks. That is exactly what I want to do. Interesting thing is that he has the exact idea I have for how to do the implementation.
