> The COI ecosystem is the COI Standard plus compatible Client Apps and Email Servers.

> COI works with all email severs, but IMAP servers can be enhanced with extra COI capability.

I’d take this to mean that no, changes are not explicitly required; but without the changes COI functions the same as email, but in an IM interface.




They have a description of the client but I could not find a description of the optional server-side enhancements (besides that it should be advertised via CAPABILITY).


Chat over IMAP seem a bit misleading title. Their proposition is to add additional info in MIME headers. Or later some of them like Message-Id with chat info. So seem more related to MIME and SMTP. A client app can get those headers with different protocols too. MAPI, EWS, JMAP, etc.


We are working on server specs, the idea is that certain functionality like WebPush, WebRTC calls, channels require the servers to support COI.


Do you know, is it going to have a demo/beta server just to play it.


Chat over SMTP/IMAP/MIME just doesn't sound right, or does it? We also thought of Chat over Email, or Chat over Mail, But Chat over IMAP gave us the COI (fish), which we love. Decision made :)


Chat over Email is so much clearer as a name.
