Dear Brian; Routers set up trees, not edge devices (such as sources). Generally, by "dual homed" you mean "part of an Autonomous System / PIM domain with connections to two or more other AS / PIM Domains." This is done by routers, so if your source is _directly_ connected to interfaces leading to other domains, it will have to act like a router and send and receive PIM control traffic. However, generally sources are not directly attached to other domains, and sources and receivers do not participate in PIM and MBGP control traffic. The internal multicast routing protocol takes care of the tree creation inside the domain, and PIM and MBGP take care of the tree creation between domains. So, this does not seem like a problem to me - SSM introduces nothing new to multicast routing. If am am missing something, please let me know.
