On the consistency issues -- we do have a mechanism for logging inconsistencies according to some rules, defined in the custom ruleset. However it only logs inconsistencies on the standard output (or some predefined java PrintStream). It currently doesn't prevent them from entering the repository. If such a mechanism would work for you -- let me know (you will need a 3.2.x BigOWLIM to have this working).
About the Lucene and logging customization -- we're on it and we haven't forgotten you :) These are still in progress. As of OWLIM-as-a-server setup -- we are usually using Sesame server as well. One possible way of speeding up the communication to this server is to use the Sesame's own tuple result binary format (TupleQueryResultFormat.BINARY) as preferred tuple query result format of HTTPRepository. This significantly reduces the overhead of serializing/parsing the SPARQL query results. Hope this helps!
