Tom Clark has kindly offered to to speak about cloud administration issues, Tom worked as a cloudy system admin in the US and currently lecturers at the Polytechnic in that area.
Tim Penhey is going to talk about his work on JuJu. The blurb off the web page explains it better than I will:
With over 100 services ready to deploy, Juju enables you to build entire environments in the cloud with only a few commands on public clouds like Amazon Web Services and HP Cloud, to private clouds built on OpenStack, or raw bare metal via MAAS.
Juju manages services, not machines.
If anyone else has a networking or other infrastructure talk in mind please let us know.
