[CalendarServer-users] Calendar Server production ready?

Hi all has anyone experiences in running Calendar Server in a productiv environment? Our goal is to setup Calendar Server on a server, which serves as the calendaring backend for a web-application. As I am new to this area, I need some advices, to decide myself. Calendar Server seems not to have an official release yet, therefore my questions. Some concrete questions: - Are the scheduling features (Invitation requests, ...) implemented and stable? - How does it scale? Where are the limits? Number of calendars, users? Any other considerations regarding a production environmen? Thanks in advance! Andreas
