Look interesting, though admittedly I am mostly interested in the open-source release of DeltaDB.

I never liked it myself, but this looks like an extension of Zed's own systems of collaborative coding (remotely), which in turn is built on top of the ideas of Extreme Programming, and / or intensive pair or mob programming.

It's interesting enough and I'd like to try it sometime, but probably only for hackathons - my main line of work is more planning than actual coding.

Certainly looks interesting and a new way of working which would take some time to get adjusted.
