Shinichi-san,
this is not possible using heartbeat at this time.
It is only able to manage two nodes. You will have problem
if you try to make it do more than two nodes.
In the future, when heartbeat 2.X is released, hopefully
late this year or early next year, this kind of configuration will be
possible.
Please not that LVS and ldirectord can however cope with
having any number of real servers so you could have a configuration
like this
node1: active/stand-by linux director, real server
node2: active/stand-by linux director, real server
node3: real server
node4: real server
...
