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.
