Networking improvements for 13.04
Our usual session for feedback on changes from the past cycle and disucssion on the upcoming changes for the next cycle.
This covers both the foundations side of things (ifupdown, isc-dhcp, ...) and the desktop side (network-manager, modem-manager, ...).
Initial list of topics:
- Local resolver on desktop installations
- DNSSEC support
- Caching support
- How to support people running their own DNS server (do we care ?)
- IPv6 support status and next steps
- IPSEC
- UEFI secureboot netboot on IPv4 and IPv6

IPv6 has now been turned on for archive.ubuntu.com and security.ubuntu.com
The next services to become IPv6 enabled should be geoip.ubuntu.com, ntp.ubuntu.com and the DNS infrastructure.
