I'm using for a suite of commercial desktop products and it's working out really well. You'll need to figure your multiple reader/single write connection pools, and graceful shutdowns in your custom server to avoid a data file corruption. This stuff you wouldn't normally do with a db server, but the discovery has made for some great learning and provided food for all kinds of load balancing and distributed db designs. Also started using fossil, which I really love for my small team. Sqlite is one of the greatest open source projects in history, with awesome docs, and really is a tribute to the art of programming. I'm happy and honored to use it for the appropriate use cases (which are a lot more than one would think).
