My 2 cents:
Fedora Infrastructure isn't going to deploy and support non free
software. Anywhere. See
https://fedoraproject.org/wiki/Infrastructure_Licensing
For some info. I think we could make it more clear though.
Even if we did deploy the zarafa-zpush stuff, it wouldn't matter to me
about sunsetting/ending the zarafa deployment. The biggest issue in my
mind is that we don't want to get into the business of hosting end user
email. There's no way to use the calendar part without having email, so
I don't think this is a good solution to our calendar issues.
I'd advise folks wanting a good calendar solution to work with the
Insight folks on their solution:
https://fedoraproject.org/wiki/Insight_use_cases_for_calendar
https://fedoraproject.org/wiki/Fedora_Insight
hopefully that will get us team and schedule calendars and we can
expand from that.
