We can certainly emulate:
port: open/binary/direct/skip ...
port: open/binary/direct ...
copy/part port ...
perhaps replacing large "copy/part" operations with a "copy/part" loop of
some sort, but I don't know how efficient this would be for large files in
a low memory environment. It is certainly something I am looking at
(including small-memory devices) along with the broader issue of, "How can
I reduce REBOL memory usage to the bare minimum?". Using REBOL/Base along
with aggressive 'unset usage is where I am starting from.

My position in a nutshell! The other case where not having direct/skip is
a pain (and copy/part is not an acceptable workaround) is trying to read
JPEG EXIF thumbnails over a dial-up line ... you have to read about 55Kb
of the file just to get the 5Kb thumbnail (160x120) you need, ARGHHH!
