I agree with Georgi. I would like to know what others think about this.
What do you actually mean by Sindice indexing Sponger proxy URIs? Are
you talking about it indexing in the same manner it does say,
PingTheSemanticWeb? If so, then you are still thinking Google / Yahoo!
style behavior.
The better way is to work like a DBMS, have a base of data and
progressively build it up while remaining sensitive to change. HTTP,
Linked Data Objects, SPARQL, and OWL collectively make it possible for
the Web of Linked Data to work like a very smart Federated DBMS.

It has to be. How would you answer a query like "all offers for a book
written by a German author" without crawling the relevant data sets?
