Please take a look at: http://lod.openlinksw.com/void/Dataset (DBpedia 
plus most of the LOD Cloud Data Sets) or 
http://dbpedia2.openlinksw.com:8895/void/Dataset (this only has DBpedia 
data). Either provides drill down oriented views of the data within the 
Virtuoso instance.

Yes, this is a good idea, one that we wanted to deliver via a query and 
save mechanism meaning: providing URIs for popular canned queries. Now 
that we can secure sparql with OAuth of FOAF+SSL these ideas are now 

btw - Not only do we want to use 404 and redirects, we also want to 
provide response data indicating if the results are complete or partial. 
If partial, then return enough information for setting appropriate 
OFFSET and LIMITs for walking DBpedia progressively, in chunks.
