Okay. First, other systems use the attendees interface to handle  
resources as well as people - I think a list on the main form with  
checkboxes is going to be really hard to use in anything other than a  
tiny installation.

> A view link is added next to each resource for the user to be able to
> view the free-busy information for the resource.

Using the attendee interface gives you the free/busy information along  
with everyone else's info, and unifies the timeslice you're looking at  
also.

For resources, they could be shares, just like calendars, but a  
separate tree of them. They'll act as owners for their calendars;  
you'll need the concept of system-owned resources for that and you'll  
probably want to hide their calendars from regular views and only  
allow looking at it in free/busy views.
