one option is to use pua_usrloc that publishes online/offline when 
location cache record is updated in some way (offline when is removed). 
You can intercept that in config and do what you want there.

Another option could be triggers in mysql, when a record is deleted from 
location db table.

Easiest way, imo, is to add an event route to be executed when a record 
goes offline. Requires some c coding, but afterwards is clean -- this 
features was listed as to-be-done in the future when event route was 
introduced, but no time yet, should be there in 3.1.0:
