[AccessD] Basic Question (Probably) that I just don't know

Hi Stuart:

I was under the impression that SQLite couldn't be used as the BE for
multi-user applications, but that web page just says it shouldn't be used
for 'high concurrency' applications.  None of my MS Access client usage
could ever be considered high concurrency (one or two people entering
orders while talking on the phone...). Have you any experience with SQLite
multi-user BEs?
