Besides analytics, seems like this could help SaaS products that want to offer a trial or demo without ever creating an account up front–just spin up an account on the fly with the uid. If they actually signup, marge their real info.
Sure thing -- I built it because I needed it, but I'm really happy to be able to share it, too.
You definitely could use this for trial/demo accounts, too. You'd want to think carefully about abuse prevention, I suspect, but in the right circumstances it could be a really lightweight way to handle this.

I'll definitely be trying this out.
