Records of our discussions are available on Google Groups under the Huge-buntu group; see http://groups.google.com/group/huge-buntu/. Everyone is welcome to participate.
Huge-buntu's primary focus is on issues of mass-deployment and -management, and long-term upkeep. This touches upon the following areas:

1.) Scalability,
2.) Ease of automation,
3.) Ease of remote diagnostics and telemetry,
4.) Customization, and
5.) Maintaining useful backports that do not entirely conform to Ubuntu's backporting criteria.

This group will interest systems administrators and engineers who maintain large deployment of Ubuntu on either the desktop or server end.
