Would these users be able to interact with the system in any way they please? 
If its not an interactive session, then I don't think its a _system_ event. 
There are perfectly fine application logging frameworks to choose from. The 
main issue is making sure that users cannot influence the records being written 
about what they are doing. 

But if you feel that you really would like to have this in the audit trail, 
then you can use the AUDIT_TRUSTED_APP event type and format the event any way 
that you wish. The audit tools sort of ignore those events because there's no 
telling what's in them.
