Hi,
because i could not have this feature, i did my own just modifying 1 file and 2 templates from EGW source files.
The goal of this module is to see the “calendar” of any contact that you can see in addressbooks ( events where the contact is participant ) and directly go to the event that interests you ( if you need to see details of this event ).
It is like last and next date module, but will give you a list of all events.
So i will share it with anyone who could need it or be interested in using it or something close from it.
I will put anything in an archive to help to make it works. ( little documentation and images )
You will be able to allow any user you want to access. I didnt manage events ACL because i think that if you want to see the details but you don’t have rights for it, EGW securities will block you. ( so no need to work more for it 
)
Feel free to test it, and i hope it will help if someone needs something like that.
Contact_Calendar.zip (483 KB)
Update: You can now download the fully working archive, there is a demo image where you will see the goal of this module.
Edited some parts because of error.
