Flashback Data Archive / Total Recall

Disclaimer:  I am not a DBA.  I am a technical/functional user looking for a tool to let me audit table changes at the row level and to report on those changes.

.

From the white papers I've read, it appears that Flashback Data Archive (FDA) is a part of the 11g database and as such does not require separate licensing. 

.

It looks like Total Recall is the only tool to use for reporting from the FDA.  And it requires licensing based on the number of CPUs.

.

Questions:

1)  Am I correct about FDA not requiring separate licensing?

2)  Is Total Recall the only reporting tool for use with FDA or are there cheaper/free alternatives?
