Please read the license before downloading JavaGroups. The most recent versions are downloadable via HTTP, however FTP may be better when downloading via a slow line. Read the installation instructions first. Documentation is available on the JavaGroups home page.
I am interested in feedback, e.g. projects in which you use JavaGroups, so please send me mail ! If you happen to have written a protocol layer and find it useful, please do not hesitate to contact me, so I can integrate it into the distribution !
