I don't know why this never occured to me before, but what happens to the Dark Energy that gets sucked into the event horizon of a black hole?

I realize this is a bit of a loaded question, since no one really knows precisely what Dark Energy is, just how it appears to effect space.

What made me wonder was the Hawking Radiation thread, and the fact that the universal event horizon appears to be shrinking (right?), due to Dark Energy. So this made me think "can Dark Energy escape a black hole", which then made me think "if it can, that's significant since it accounts for the bulk of the Universe."

Anyway, thanks for any help, even if it's "who knows such things?"

What is it that makes you think Dark Energy is attracted by gravity?

Well there you go. The (apparently) only thing in the Universe that isn't attracted by gravity, which means that most of the Universe isn't attracted by gravity.

Which renders my point about event horizons moot, but makes Dark Energy even that much more enigmatic, if it's true.

Dark Energy seems to manifest as the vacuum fluctuations throughout, and expanding, space. In the casimir effect experiment the two objects are close enough so that the vacuum fluctuation cannot manifest between them, but still does all around, the resultant force pushes the objects closer to each other. So in a neutron star the same thing would occur; the vaccum fluctuation couldn't manifest because the mass is too close together, similarly once through the an event horizon the effect of a blackhole, the condition would also exclude the vaccuum fluctuations, aka Dark Energy.

Therefore space would expand around the blackhole, but itself would not expand at the same rate, effectively shrinking.

as I think I might understand it..

How far apart are the surfaces in the Casimir experiment?

The Casimir effect can be explained using electrostatics.

Dark energy is invoked to explain the accelerating expansion of the universe, not to explain the Casimir effect.

Have a look at this.

The distance between the ball and plate is 0.1 micron in this article that links to that page.

That article has a good experimental history, no mention of electrostatics though, I think that is something else.
