Here's a quick thought about a new functionnality that could be added to the license server.
What about allowing the server to provide default settings to user installations?
When somebody installs a new copy of IDEA and enters the license server's URL, the panel could ask the user if he/she wants to download the default settings that have been configued. If he/she says yes, then it would download a settings.jar archive and import it automatically.
The import mechanism would be the same as today. On the server part, we would just need to specify a JAR that has been generated by exporting the settings of an existing IDEA installation.
Basically, today a new installation requires the two sames steps: enter URL and import JAR. This functionnality would make things faster.
What do you think?
