All of the mentioned items above are available via settings in the console.

You create a streaming package and load it onto the server via an admin console.  You can then "provision" users to have access to the applications.

There are also many settings for each package.  You can have the streaming client on the workstation only display the icons for the package when  provisioned user logs in.  You can also have the client begin streaming the entire application when the user logs in.  You can set the package to be available offline only, online only or offline if a laptop.  In this case, the entire application will stream to the client machine allowing the user to use the application when the machine is not connected to the network.

The application will retain its state through a reboot as well.  However, there are package settings for "idle time" where you can set the amount of time an application remain idle (not used) before it is reclaimed from the server.

Hopefully that answers you questions.  If not, let me know.
