Gnome 3.0 : User account online

[informalibre montceau <informalibre montceau gmail com>]

Hello,

 Gnome 3.0 on a magnificent stuff that we could have would be a management user account online.

 I explain how it works:

 I created an account on Gnome.org via "online account",
 and then the data is synchonisées with this online account.

 Among the data:
 - The list of installed programs
 - Email and preferences of "evolution"
 - The list of extensions gnome-shell
 - The favorites of "web"

 So just the data that does not take up space but can set their computer if reinstallation.

 See to connect from another computer via gnome 3.0 a temporary account.

 Can you do echo of that for me.

 Thank you in advance
