I know why Luci is doing this -- she sees the cluster reduced from three 
nodes to two nodes and configures it (as the large majority or our 
typical users consider) appropriately. When you are finished maintaining 
the node and you tell Luci to add it back in to the cluster, she will 
remove those configuration attributes.

The sticking point seems to be your particular desired cluster behavior 
and the fact that it lies outside of what was expected for cluster suite.

If this is not appropriate behavior for you, then don't use Luci. You 
are free to use a text editor on the cluster.conf file and propagate it 
manually via the command line on one of the nodes, as you are free to 
edit the source code and add ssh support to your favorite fence agent. 
You are free to go off the map, and the members of this list (including 
many of the Red Hat engineers who write cluster code and watch this 
list) will assist you in your expedition as much as possible. We will 
all try our best to help you get where you want to go (and I think you 
would have to agree that you have had a very respectable response rate 
for your queries this last month - many have tried to offer you 
assistance), but if we can't think of a way to stretch the software to 
your needs, then we just can't.

I do want to disagree strongly, however, with your blanket suggestion 
that this software is not complete, and is not a cluster solution. It is 
a solution for many, many users...not all of whom are RH customers. It 
is just not a solution for you, my friend.

Thanks for your many constructive comments. I hope you keep trying the 
software - we are here to help as best we can. I haven't given up on you 
*quite* yet! :)
