Hmm. I'll look into that. Note, we don't publish a VoiD dataset for this 
instance. It has 50 Billion+ triples in place already. That said, there 
is a Provenance oriented Linked Dataset derived from it (and other data 
sources) by Tim Lebo [1][2].

Bio2RDF is one of the original Linked Data publication efforts (pretty 
much unleashed around the same time as DBpedia). Its datasets are 
comprised of data collected from may sources from the realm of life 
sciences.

Linked Life Data is a similar effort to Bio2RDF i.e., yet another 
dataset comprised of data from various sources in the life sciences realm.

OpenLink Software is a company that develops the DBMS and Linked Data 
deployment technology known as Virtuoso. For instance, Virtuoso 
instances are used to deploy most (if not all) of the Bio2RDF instances 
(which include SPARQL endpoints and Faceted Browsing front-ends). 
Likewise, it is also used to deploy the DBpedia and Linked Open Data cache.

Think of Bio2RDF, Linked Life Data, and the LOD Cloud Cache as Web 
accessible DBMS instances accessible via SPARQL compliant query 
interfaces -- exposed by SPARQL endpoint URLs.

You can access, merge, reconcile data across these DBMS instances, using 
SPARQL.

What if I eventually want to use a crawler like LSSpider instead of dumps, so that my results stay up to date? I would assume that these are all questions that application developers who want to use Linked Open Data would be asking.

Yes, but I am sure you can see your demands aren't exactly questions 
with simple yes or no answers :)
