Film scanning is dead.

film is dead.

But not forgotten. Which is exactly why it is (sometimes) worth copying
before it decays.

definitely.

Digital ICE's in the hardware. The soft do or do not support it.

digital ice uses infrared light for dust removal, created by applied
science fiction (awesome company name), later bought by kodak.

vuescan has its own implementation of infrared dust removal.

It does not. Vuescan uses the infrared channel created by the scanner

subtract dust. I.e. ICE...

that's what i said:

such as vuescan's equivalent of
digital ice.

Your wording suggest that you think that it's not. Whatever...

it's not exactly the same. it's equivalent.

From the main wiki:

"The ICE technology works from within the scanner, so unlike the
software-only solutions it does not alter any underlying details of the
image. Subsequent to the original Digital ICE technology, which used
infrared cleaning, additional image enhancement technologies were
marketed by Applied Science Fiction and Kodak under similar and related
names, often as part of a suite of compatible technologies. The ICE
technology uses a scanner with a pair of light sources, a normal RGB
lamp and an infrared (IR) lamp, and scans twice, once with each lamp.
The IR lamp detects the dust locations with its unique detection method,
and then inpainting is applied based on this data afterwards. The
general concept is to subtract the position of scratches and dust from
the RGB image."

...Some software algorithms, such as the latest ICE implementation
(Nikon Super Coolscan LS-9000 ED with Digital ICE Professional[3]),
VueScan's[4] and SilverFast's,[5] claim to use infrared cleaning to
find dust spots even when scanning Kodachrome.

When an infrared channel is available, use this option to remove dust
spots and scratches. It only causes image softening in the immediate
vicinity of the spots and scratches, except when this option is set
to "Heavy".

http://www.silverfast.com/highlights/isrd/en.html
...iSRD utilizes this behavior as follows. The image is scanned two
times - the first is the regular RGB scan and the second is the
additional infrared scan that captures defects like dust and
scratches only. Then the calculative dust and scratch removal takes
effect, only where the infrared channel has detected any defects
without losing any important details.

An equivalent to Digital ICE would not be that but something else.
Vuescan and the others above might have slightly implementations of
Digital ICE...
