I agree with Stephane. You can easily just audit user connections. You can see how many distinct usernames appear over a given time period to help determine who is actually logging in (or trying to). To see who is still connected search where logoff_time is NULL.
To audit connections use AUDIT SESSION. This audits all new connections from that point forward. Use DBA_AUDIT_SESSION to view the audit trail (not sure if this will work if you send the audit trail to the OS). Finally, I would definitely formulate a plan to remove entries from the database audit trail, sys.aud$. Monitor it's growth daily to help determine how long you want to keep records. At that point either copy to another table and then delete entries older than a certain date or something. You can answers many questions with this turned on. P.S. Make sure the instance init parameter AUDIT_TRAIL parameter is set appropriately and the instance needs to be rebooted for this to take affect (only downfall).

Why do you say that auditing will be an overkill? You do not have to record everything. You can have as little as storing a row into SYS.AUD$ each time somebody connects.
