The problem as I see it is that RDBMS handle also all the transaction, 
clustering, caching, replication, backup etc. This makes for a lot of 
complexity. If we do the same in Jackrabbit this means that we will be 
reproducing a lot of what lower storage systems (like JDBC) can already 
do no ?

Just trying to understand :)
