Thank you for your answer, and thanks for your huge work in involvement 
in this.

1 - Is everything ready in RoundCube, to allow a smooth and well 
integrated calendar and contact plugins using CalDAV and CardDAV ?
2 - Is there enough plug-in hooks and documentation and flexibility to 
allow this? For instance, is it possible to make sure a calendar 
invitation is displayed correctly, that the entry will be added in the 
calendar and a confirmation email sent, when I press "accept"?
3 - Is there a way to get free/busy times from the address books when 
organising an event?

More generally, is there any organised collaboration with the current 
plug-in developers to make this happen? Why I have the feeling that a 
lot of calendar plugins are regularly out-of-sync with the roundcube 

If I want to add a calendar to my Debian server, I will end up using 
Sogo, which I don't find as convenient as RoundCube.

Kind regards,
