Currently, GlueDomains in deployed on about ten hosts, and is included in the GridICE Grid Management project.
The site in Bologna supports the GlueDomains database server, and tests are performed in a complete mesh.
The first official release came after (only) four testing releases, with no substantial rewriting required so far: mainly each new test release introduced new features.
The architecture has proven to be reasonably GMA-independent: from 1st to 2nd testing release we replaced a R-GMA plugin with a MDS oriented one, which publishes through the GridICE GMA.
The current distribution is RPM oriented and self-installing: to install a new monitoring host, the local administrator simply installes the required packages, and untars an archive containing a few sensible items, like database passwords.
