Thanks. Unfortunately, I'm trying to stream large files across the
network; the time to throw away the first 4 megs of the file would
really slow things down.
I guess I can prototype the streaming protocol in C and just control it
from Rebol.

The FAQ example shows using a command sequence like
file: open/binary/direct %myfile.txt
skip file 2000
Which just hangs on the skip command.
