I'd already started to write a crude version of this. Now I don't have to. It had me confused and feeling stupid at first, but now I understand how to use it. I was just creating my DBs in code and will continue that in my final program. But having a tool like this is very useful during development.
I see they've stress tested SQLitening with 500 bots hitting it at once and it didn't miss a beat. That should translate to about 5,000 to 10,000 users per host in my scenario. I can be a success even if much less. Now back to work. Grindstone... nose!
