[kronolith] Auto shared calendars

[Mario Andres Yepes C]

Greetings.

Im traying to hack kronolith into an Academic aplication where students and 
teachers can share calendars and I need this to be automatic.

Example.
When a Techers logs into horde and selects kronolith, in the list of clendars 
there is a calendar for each asignature with read/write permisssions. When a 
student logs into horde and selects kronolith, he/she sees the calendar for 
each of asignature with read permissions.

Any pointers on how to achieve this?? I know that this is goal is not 
reacheable by tweaking the configuration files, but Im willing to get into 
the code and submit a patch if its convenient for the project.

Regards
Mario
