I need some ideas on this. Feel free to shout out good, bad and ugly 
suggestions that come to mind. I'm sure something will stick to the wall :)

This is in regards to: https://bugzilla.redhat.com/show_bug.cgi?id=662118

Here's a screensnapshot to get an idea how the JSF UI did this: 
https://bugzilla.redhat.com/attachment.cgi?id=368720

Consider: you have a compatible group with N member resources (each is a 
JBossAS Server resource). One member of the group has a child resource 
called "run.bat", but another member does not (this happens when one 
JBossAS instance is running on Windows, and another is running on Linux).

In the "cluster" group view, you see a child node like this (see 
snapshot link above for the real example of the tree in this case):

    run.bat (1/2)

It's the "(1/2)" that we want to "make better". Do YOU know what that 
means :) That's the problem. It is hard to understand the semantics of 
this. What the 1/2 means is "there is only 1 run.bat child resource out 
of the 2 total members of the group".

How can we render this information better? How can we indicate the tree 
node you see in the group tree represents a "partial" child - that is, 
we need to be able to say "some of your group members are missing this 
child".

Tooltips, additional labels, image badging, a combination of these? We 
need some mechanism to convey this information, I just don't know the 
best way to do this :)
