I have included the idf file in my uploaded files folder: http://tech.groups.yahoo.com/group/EnergyPlus_Support/files/Variable%20Flow%20Chilled%20Ceiling%20/
Keep in mind that the results from this idf will look different than the results shown from the previous posting, because this idf file is just for a test zone (although, it is the same HVAC system, construction, internal loads, etc.)
I am using the San Jose, CA TMY3 weather file.
