You will also need to set the 'Cached' bit for this to work properly.

Actually, you can do it from any station that has write access to the
file, regardless of whether someone has it open. I don't think it will
take effect until the person who currently is using the application
quits, however.

Most relatively new applications don't exhibit these problems. I've seen
MS Word, Pagemaker, Freehand, Illustrator 88, Cricket Graph, Excel,
and even new versions of MacWrite work successfully with this. My failure
to mention a program certainly doesn't mean it doesn't work this way;
just that I haven't tried it (and yes, the site does have licenses for all
the stations using the software. And you should too, or else you're
violating the software's licensing agreement. Even using it this way on
a network when you do own enough copies may be treading on thin ice; I'm
not exactly sure).
