I understand you so:

a.) There is enough know-how for running heavy SPARQL endpoints.
b.) But there is no enough money.

I cannot help in the way you think, because we work in different areas.

I can access different SPARQL endpoints with different lists of queries  
with a mouseclick under a single user-interface (surfing rdf-data with  
'similar' ontology structure) and i can write comments to you or to  
fitting mailing-lists as i did it yesterday, that's all, sorry,

thanks, baran.

PS: Also thanks to Kingsley Idehen for interpreting 'HP of grandma' as a  
friendly methaphor.
