This views value as a sort of metaphysical substance that can be produced. This
is at best no more than a metphor and extended to the subjects that dave raises
it is a misleading metaphor.

One should not talk of value being produced.

The labour value of something should be seen as its cost in Smith's 'original currency' : labour.

Asking how much the labour value of something is amounts to asking how much of society's labour must
be devoted to producing it. It is not a question of labour 'producing' value, but of reproduction
consuming labour. If you think in terms of labour producing value you have an unecessary doubling
of entities - the labour and the value.

I'm not sure what you feel the problem is here.  The commodity LP 
does NOT have to be sold at its value: i.e. LP, like every other commodity,
can be sold at a price greater or lesser than its value. The proposition 
that LP is sold at its value is assumed to be the case on average, but
there can (and are) temporal and spatial causes for disparities between 
the VLP and wages: this has important meaning for comprehending 
regional and urban issues.
In the example above, the nominal wage is the same and so V is 
the same.  C is also the same. And, following your lead, the working
day (and the intensity of labor) is the same. So, why would S change?

One could recognize, instead, that necessary labor time can itself
be relatavized.  
If we follow your alternative, then surplus value can increase for no
other reason than capitalists increase the prices
of commodities sold to workers.  This creates the possibility of S
being increased simply through a greater mark-up of commodities 
over cost.  Another way of looking at this issue, though, would be
to recognize that there can be disparities between S and profit.
Perhaps the subject of rent should be included here.  If workers
have to pay a higher amount for food, then one might conceive
of this as a short-term transfer of value from workers to food-
producing capitalists or landowners.

Ah, this raises a throrny issue: does non-wage labor which does not
create commodities still create value?  It is true that there is labor required
to produce the commodity LP and that much of that labor oftentimes
is non-waged.  But, we have to recognize that _if_ LP is a commodity, 
then it is in some senses a _unique_ commodity.  Of course, one could
challenge the claim that LP is a commodity (as OPE-L member, Mike 
Williams has done) or one could offer alternative explanations which are
more or less satisfactory depending on your explanation and perspective
on value.
In solidarity, Jerry
