I had assumed that "Datomic <i>in</i> the browser" meant an implementation of Datomic that actually runs in the browser (presumably written in ClojureScript, though not necessarily). In fact, this looks more like "[Accessing] Datomic <i>from</i> the browser".<p>Aside from that, this does look genuinely interesting. I'd like to see more information about how people are using Datomic - I've evaluated it briefly but never saw a good enough reason to move away from familiar relational databases.
