I plan to finish the work I started on ZEO to port it to asyncio, as I'm pretty far along. In addition to moving to a modern networking library (supporting SSL), this will allow me to greatly simplify the ZEO implementation, which is something I've wanted to do for some time. (I expect that when I'm done, someone else will port the asyncio code to Trollius to get Python 2 support.) As part of this I'll likely make ZEO a little bit more like NEO: - Per-object rather than global server commit locks, and a shorter window for commit locks. - Moving conflict resolution to clients by moving conflict-resolution handling into ZODB itself, probably through some pluggable mechanism outside the storage layers. This should allow some simplification of NEO and Relstorage. I also plan to devote a lot more time studying NEO. Maybe someday NEO will replace ZEO, or maybe ZEO will serve applications that don't need multiple servers. We'll see.
