It's the second day of the Lemonade Interop in Munich. We've lost a client developer since yesterday, as as a result clients no longer outnumber servers - instead we're neck and neck, although this counts neither the several remote participants, nor the local presence of a mobile email service provider, Momail.
Interestingly, some of the very latest work is being actively implemented and deployed. For example, Philip van Hoof and I both have the QRESYNC extension for single-round-trip synchronization implemented in clients, and we've four servers to test against. It's impressive seeing a crowd of clients in the room implementing some of the most advanced tricks in the Lemonade book, not only forward-without-download, but CONDSTORE is now routine for advanced clients. I'm particularly struck by the immense progress that's been made since last year, and the increased interest from other client (and client framework) developers too.
Interesting, too, the discussions we've been having over technologies like CONVERT - which would provide the kinds of content conversion on demand that Momail are providing their customers automatically. We've a server implementation of it, now, and the lessons learned - and input from Momail - has been fascinating. NOTIFY, too, as well as the overall architecture of the "Push" email that's in demand from many people, has been carefully looked at.
We're coming to an end, as I type this, having overrun by a little while, but it's been a great time, and it clearly demonstrates that Lemonade is very close to widespread deployment.
