So ZeroDB is a fork of Zope's ZODB! I had watched a ZeroDB fintech pitch on youtube a few weeks back and had no idea. I can understand the USP: cloud DB hosting for sensitive data. Even though I'm a long time Pythonista I can't help wondering about the performance implications. IIRC ZODB did have some C optimisations last time I looked at the code, which was back in 2001/2 (yikes!)
