Why are you telling users to cripple their database by using MyISAM? They should be using InnoDB, though honestly SQLite would be quite sufficient for something this simple.

Or you can do what I said, which is simpler and doesn't add another dependency.

No, this is ridiculously over complicated, if your NAS supports interim updates just do it how I said.
