5b - I keep my SQLite stuff in a Dropbox folder. For a few years I had two PC's running the same stuff. Usually I would close my app on one before starting up the other. A few times I didn't and ended up with a "conflicted copy" of a file on one PC or both and had to try to figure out which version had what. But in general things worked pretty well. There was never a serious problem. If only one PC (at a time) is making changes, and other accesses are read-only (as my workload has been for some time), I do not anticipate any problems at all.
