Looks super interesting! I'm quite literally the ideal user you describe, and I can't wait to try this out. If I can get any meaningful outputs from my databases thank to mindsdb I'll be super happy.
Also, good idea the hosting, I am currently struggling in training my models as I don't have the needed processing power, instead of bulding a new PC for ML tasks I would very likely happily consider hosting the heavy lifting. I'll keep an eye on the release.
