Yeah, that's a neat project. I was already thinking about building this before they launched, and their positive reception spurred me on.
If you're already using Heroku Postgres there's a ton of overlap between the services, but I'm hoping to provide a decent open source alternative for the rest of us. :)
Author here. I do a lot of analysis each day and am constantly sharing it with my team by taking screenshots of Sequel Pro. I built Oculus so I could keep a centrally available repository of my research, that everyone could access and collaborate on. It definitely has a ways to go, but I would love feedback!
Also, this is my first attempt at providing a live demo of software that can execute arbitrary SQL. I'm probably crazy for doing this, but I thought it was a lot more interesting than doing a video. If the demo suddenly disappears, you'll know I wasn't able to harden it enough... :)
If you can run Rack apps in your environment, it would be pretty straightfoward to add a SQL Server driver to Oculus. Right now it supports MySQL and Postgres.
It's designed to be used within a team environment, where you trust everyone. (Although even then, I highly recommend using it with a readonly SQL account!) I would be skeptical of any situation where you could run raw untrusted SQL without any risks, at least without reimplementing MySQL's AST parser.
As for the demo, it's isolated, and locked down as well as MySQL will allow. (For starters, just SELECT privileges.)
