I'm following up on my own post... again...
I figured out what was wrong, and have ammended the code snippets
below (for posterity sake... for all others that may follow.)


--------- packet-sita.c ----------

disect_sita() {
...
   if (!dissector_try_port(sita_dissector_table,
       pinfo->pseudo_header->sita.proto, tvb, pinfo, tree)) {
     call_dissector(data_handle, tvb, pinfo, tree); /* default decoder */
   }
}

proto_register_sita() {
   proto_sita = proto_register_protocol("SITA", "sita", "sita");
   sita_dissector_table = register_disector_table("sita.proto",
      "ACN protocol number", FT_UINT8, BASE_HEX);
   register_dissector("sita", dissect_sita, proto_sita);

}

proto_reg_handoff_sita() {
   sita_handle = create_dissector_handle(dissect_sita, proto_sita);
   dissector_add("wtap_encap", WTAP_ENCAP_SITA, sita_handle);
}

--------- packet_ipars.c ---------

proto_register_handoff_ipars() {
   register_dissector("ipars", dissect_ipars, proto_ipars);
}

proto_reg_handoff_ipars() {
   ipars_handle = find_dissector("ipars");
   dissector_add("sita.proto", ACN_PROTO_IPARS, ipars_handle);
}
