I would like to thank you for your example - saved me a lot of head scratching :)
I had started on doing an example with these two plugins only a few hours ago, and found your example when I was looking for more information.
I hope this update is of interest to you. 

Updated server and cookie plugin support a route specific redirectTo false so isLoggedIn is available and correct rendering route /.
Added isLoggedIn to template rendering context.
Added nav.html for the isLoggedIn case.
Moved lout require down to register of plugins like other plugins.
Fixed a few spelling errors.
