Re: [ARSCLIST] long range file storage
I would have thought that the issue would never even come up as long as it's all part of the same organization. Learn something new every day, I guess.

I heard from Greg Lukow on this matter. He seems satisfied that these are
the same entity and thus ok.
I recall concerns being raised about this issue in a presentation to MLA
about buildings on diferent parts of the Indiana University campus. Theirs
was a "one building" rule at the time. I don't know if has been altered
subsequently.
