I should be able to help out testing, debugging, etc. since we really
use the aggregation capability on high-volume systems and therefore
have a big data store to use in testing.

I'll try to take a look at this.

I was thinking that it seems to me a relational DB would be a help on
this point. Rather than parsing the entire log structure every time,
perhaps the audit-viewer could just query for the desired data and try
to leverage the DB's optimization.
But I guess if you went to such a big change there you might also
consider making it network-capable similar in form and function to the
prewikka viewer. This one handles large amounts of data pretty well.
