I waited until you had an answer to say this, but I'm also doing this.
Someone else spent 5 minutes doing the hard part, and now it works (using
linked tables).
My main goal was KISS (keep it simple) basic security. Can't find a way to
keep even a non-sophisticated person who has access to an Access database
from simply copying and taking the entire database. For the 99% of people who
don't have the time to make a life out of learning it, Microsoft security
mostly just stops things from working rather than providing security.
