An idea I have heard is to use as the multicast address for "ARP-FOR-PROTOCOL-X" is <4-bytes-of-multicast-prefix><X>, i.e. ARP-for-IP 01-00-5e-00-08-00 ARP-for-CHAOS 01-00-5e-00-08-04. If you are a host listening for ARP on protocol X, you fire that up. That means IP requires 2 multicast filter slots to get off the ground (1 for ARP, one for 'IP-all-hosts'), plus any other multicast groups that it may join, plus multicast groups for other protocols (ISO-all-hosts, etc...)
