OK. HERE is a link to the demo.

Its pretty crude at the moment, but it shows a promising proof-of-concept.

Ive got a few ideas for improvement Ive yet to try, but
because Im new to working with VIEWs, I am unable to estimate
what sort of horsepower this process is going to require.

I havent detected any noticable load, but as you can see, its
only a very simple level with only one active entity.

Ideas anyone?
