Yep, I see it!  What's the best way to tell how much memory or how many pages 
are being shared?  Will Xen's memory status (e.g. with xentop or xm list) show 
lower memory usage per machine?  Or is there somewhere else I need to dig to 
find how much memory is shared?

I think the RPMs I have are built without this - I cannot seem to locate it.  
I'll have to see if I can compile it myself.
