a simple method for handling calender permissions.
ie, private calenders, public calenders, and limited access calenders
radical is easy to install, but working out permissions for
editing/viewing I found less than simple.
having permissions, or at least login tied with dovecot reduces password

It may be able to be implemented in a text file or sql table, but I'm
not sure how the mua's handle adding entries/calenders/changing
permissions etc. If it would work for thunderbird and ms outlook, it
would cover a large section of the local userbase that may use it, and
working with squirrelmail and roundcube would cover most of the webmail
