Correct me if I'm wrong, I think SOLR-303 is focusing on merging results from multiple shards right now. We'd like to start an open source project for a fault-tolerant distributed index system (or join if one already exists) if there is enough interest. Making Solr work on top of such a system could be an important goal and SOLR-303 is a big part of it in that case. I should have made it clear that disjoint data sets are not a requirement of the system.
