Remarks
An SPReusableAcl object is an opaque object that an application can use to return a Windows SharePoint Services object that represents an access control list. The SPReusableAcl object can be stored and passed back to Windows SharePoint Services for permission checks, and therefore, the object is considered "reusable."
Use the ReusableAcl property of the SPWeb, SPList, or SPListItem class to return the ACL for a Web site, list, or list item. For any class that implements the ISecurableObject interface, you can use the ReusableAcl property to return the ACL. To return the ACL for a site collection, use either the GetReusableAclForScope or GetAllReusableAcls method of the SPSite class.
