August 11, 2010. OSCgroups source code is now hosted on googlecode at code.google.com/p/oscgroups/
October 17, 2005. The sources for oscpack and OSCgroups are now harmonised, so you can safely use released versions of oscpack with oscgroups.
OSCgroups is a system for routing OSC messages between a group of collaborating users. It is designed to make joining and leaving a group simple, and to overcome the problem of connecting multiple users behind different NAT routers using a NAT traversal server with the usual “NAT hole punching” scheme (you can put that into google for more info). OSCgroups also implements basic group functionality similar to the concept of channels in internet relay chat. You can read the README file for more info.
OSCgroups is currently being used by researchers at the Music Technology Group, University Pompeu Fabra, for teaching at Georgia Tech and Mills College, and is also part of the Hub’s current networking infrastructure. The software works, it’s been used for performances. The server has mysteriously fallen over twice in the last six months, so there is a suspected bug there. If you need to reboot the server at short notice you should run your own. Code reviews and bug reports will be happily received.
OSCgroups has been compiled and used on Windows, Mac OS X and Linux. It should also work on 64 bit platforms, although this has not yet been tested.
Recent OSCgroups snapshots can be downloaded below. The filename format is year_month_day_hourminute. In the Subversion repository (see below) interoperable versions of OSCgroups and oscpack are tagged with the same date/timestamp.

Thanks to University Pompeu Fabra for the public OSC server.
Thanks to Tim Kreger, the guys from the reacTable, and the Hub for being beta testers and helping with cross platform debugging issues.
Completed at the Music Technology Group, Audiovisual Institute, University Pompeu Fabra, Barcelona, June 2005.
