In the 10.10 release, Unity on the netbook edition used ConnMan. As Unity is now moving to the desktop for 11.04, will that mean that ConnMan will replace NetworkManager on the default Ubuntu desktop as well?
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.
There are many reasons why indicator-network wasn't made default in the Natty release:
1) Doesn't support all encryption options (you already mentioned that in your question).
2) Hasn't been tested heavily (its a new project).
3) Ubuntu has been using nm-applet since quite some time, and hence it was much better for them to just port it to the indicator rather than start from scratch.
Probably indicator-network will become default in a future release of Ubuntu after it meets all of the above points. Good things take time to come by™.
