No, it would work for VMS, and level 1 at least would work for RSX, but neither
RSTS nor RT11 understand it. And it's a complex file system, more so than the
RSTS one and vastly more than RT11. It does more, of course, but if you're
looking for something that can easily be ported to another system, this won't
do.
I took the proposal to mean: find a simple OS for which you can easily
implement an application to handle it on most operating systems. So think
something handled by an application like PDP-10 FLX (or RT-11 FLX), not a file
system with native support.

One key question is how important it is to transfer a bunch of files all at
once. Is it sufficient to send one file at a time? With scripting, that may
not be all that problematic.
