If we want to have a live DBpedia endpoint that serves the whole world, we have to have it configured in such a way that it forces use of OFFSET and LIMIT. We are very experienced with DBMS oriented data exposed to massive concurrent users, and this stems to periods prior to the pervasive Web of today, thus we've configured the DBpedia SPARQL endpoint with this experience in hand. Once again, the DBpedia endpoint is for everyone, so we deliberately protect against inconsiderate use e.g. attempting to get massive results sets in single query passes at the expense of others. Also remember, you can make application or service specific instances of the DBpedia SPARQL endpoint via a number of offerings on EC2 if you seek hassle free reconstruction of DBpedia.
