Will ConnMan replace NetworkManager on the desktop for 11.04?

The systray (old notification area) will go away in 11.04. NetworkManager is the most critical piece that still uses it. We have three options:

• Move to the new indicator-network which uses Connection Manager as a backend,
• Provide patches for NM-applet that enable it to use the AppIndicator framework, and
• Hack the systray so it only supports NM-applet

The Ubuntu Platform team is working on the NM-applet-indicator option, and it's their decision which approach is taken in the final release.

No; the plan seems to be to enhance indicator-network / patch NM to use NM as a backend.

There's no blueprint yet, but the content of the Gobby document from UDS is here.

See Mark's answer for details.

I second that, there is no plan to make the new connman-based network menu the default for Natty.
