Version 2.0 of the Open Mobile Alliance's Digital Rights Management Specification provides for protected content to be shared amongst a collection of devices in a domain. Domains are created and managed directly by the rights issuer that issues rights to the domain. In this paper, we propose to devolve the management of domains to a domain manager known as "Heimdall" that acts as a broker between the devices in an authorised domain and any content providers from which content for the domain can be sourced. We describe and compare three different modes in which Heimdall might operate.
