There are several server parameters that will be important to hosting institutions, which presumably could be queried during installation and then modified later if needed.
Restricted user email addresses. For example, users must have email addresses that end in "hanover.edu".
Extent of command-line access. Default will be not to permit access to any kind of command-line access to R because of the security risks. However, within some organizations (highly experienced users), this should be permitted.
Maximum number of simultaneous users. It might be helpful to include a monitor tool so that administrators could track usage over time and see if they're getting close to maximum.
Timeout for session. How long the server will wait without a response from a client before closing the connection.
