Giving Everyone Limited Access
With the new grants system you don't need to create a group for 'everyone', and make everyone a member of that, you can just set a default privilege on your principal record, and that will be the privilege that applies to anyone who is not granted a specific privilege.
This is often a good way to set free/busy privileges, in a larger organisation, or read-only privileges, in a smaller one.
Granting Everyone Read, Restricting One Calendar
If you set a default 'read' privilege on your principal, you can set a specific grant of (e.g.) free/busy on a calendar and that will mean that people can only see free/busy times on that calendar and not the actual content of the events. Or you could deny them any access by specifying a grant from the calendar collection which granted no privileges.
Specific grants will be used instead of default privileges, if they are present, although if a user has several specific grants, such as some directly, and some via a group membership, then the applicable rights will be the sum of all rights granted (except the default ones).

If you're not sure you got it quite correct, or you have something you don't know how to do, write it up anyway and then head over to IRC or e-mail the mailing list to ask for someone to review your recipe.
