Lou,
I have ben positing this with respect to DCE, the change in casimir
geometry and therefore the restriction of virtual particle sizes is just such
a Maxwellian demon. Powered by change in geometry it creates boundaries that
react asymmetrically to atoms vs molecules. It doesn't sort hot from cold but
it sets the stage for discounting the disassociation level of molecules while
ignoring atoms. If the area is heated such that the molecules approach
disassociation this asymmetrical opposition to molecules will discount the
threshold opening the door to over unity at the cost of geometry. I am
convinced more heat can be released upon reassociation then the discounted
value achieved by geometry and random motion of gas. You are essentially
putting the random motion of gas in opposition to these geometrical boundaries.

Subject: EXTERNAL: [Vo]:More versatile Maxwell's demons
Those interested in thermodynamics may find the following worthwhile:
Some recent papers showing that Maxwell's demon may not require energy -
"Single-reservoir heat engine: Controlling the spin"
http://fqmt.fzu.cz/13/pdfabstracts/605_1f.pdf
"Beyond Landauer Erasure"
http://www.mdpi.com/1099-4300/15/11/4956
The latter is part of the journal 'Entropy'
- Special Issue "Maxwell's Demon 2013"
http://www.mdpi.com/journal/entropy/special_issues/maxwells_demon2013
The following paper shows that computation needs no energy - if reversible.
"The Connection between Reversibility and Heat Generation"
http://people.ccmr.cornell.edu/~clh/p562/TPH/Bohn_TP.pdf
Whether a spin (or other conserved quantity) reservoir can be created (or
discovered) for less than the thermodynamic energy it returns in a novel
engine is an intriguing question - and, also whether such engines can be
scaled to macroscopic size.
