I am still confused about what being articulated above. Please note, 
I've been designing and using data access virtualization layers (in 
various guises) for 20+ years.

Let me ask my question differently: in a world where structured data is 
accessible via HTTP, query services (like SPARQL), and constrained by an 
abstract data model (e.g., EAV, RDF etc..), is there any reason for 
MongoDB needs to be in the conversation re., Javascript based libraries 
and frameworks aimed at data access?

I have zero interest in platform specific technology, once I smell leaks 
in abstraction I simply move on. I need to know if I should invest any 
of my time looking at this work. Bottom line, can I get this stuff up an 
running without MongoDB or any other platform specific bits (e.g, 
nodes.js) ?
