I was describing the behavior, not the intent. I've no doubt they would
have enhanced the syntax over time. I don't think that hardware limits
had anything to do with it. At base, ARC was not a networking
(distributed processing) project, in spite of the fact that the SRI guys
were heavily involved in the networking work. Still from my
recollections of their work, I believe the incremental processing for
going cross-net to access documents wouldn't have been all that onerous.
Rather, the project wound down about the time I'd have expected that
enhancement to be pursued.

Initially, yes. But they eventually supported remote IMLAC graphics
stations across the net. Somewhere around '73 or '74 I was a beta
tester for it, down in L.A. It's when I first learning how challenging
a mouse-tracking algorithm can be in a noisy environment... (It's also
the only time I needed to write a machine-boot program.)

I didn't. cf, my note to Tony.
