Add support for DAViCal and how?
 

I propose adding support for DAViCal to ISPConfig3. :)
But the real question is how should it be done?

Should it be an add-on like a package?

Should it be integrated?

Here is the project page if you would like to check it out.

I'm thinking that it should be an optional feature so a package would be more likely. Anybody else have any thoughts?
