IGMP lets a router know that there are devices on one of its segments that need to get a particular IP multicast flow. If you don't have routers, you don't need IGMP. Switches by default flood multicasts out every port. You can constrain this with VLANs, so you would want to know about any VLANs in use on your switched network. But, in general, multicast just works on a switched network. There may be specific applications that wouldn't work due to brain-damaged implementions (that depend on IGMP regardless or something), but theoretically you shouldn't have a problem.
