We have done it for an (closed to the public) e-commerce solution which 
could not be done with http-authentication (we have 2 user-names and one
password for authentication for historical reasons)
Se we needed a solution and found it as a simple solution with the
standard
header of all documents wich include some kind of session-management
down
the protected path. If the user is authenticated, the session management
keeps
track of it and provides useful data to all pages where it is included.
If the session is timed out or a not authenticated user tries to access
some
pages, the session-management (a dtml-method) sends a redirect to 
the login-page.

I can give a more detailed description on request. 

But at least: yes, you can do it; yes, it makes sense
