Note that you can use traceanalyser and other things, see metalink notes 279132.1 296559.1 224270.1 62294.1 1058210.6 etc.
The login trigger could play games with
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sessio.htm#i1010942
setting context to something unique to help winnow trace files.
Perhaps you can scope by identifying the session with some special user inquiry, then only turn on tracing for that session.
I guess it depends how cooperative your users are!
Pound on the vendor to have the app load up some program/terminal information.
