Dear JVP,
Re the article: none of that will seem "innovative" to anybody who is familiar with persistent cursors or cached tables as offered by FP since 1988. The only specific difference I see is the enforced split between memory and disc "caches", which is of course an unfortunate complication of the (current) lack of a local data engine in dotNET.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
