Revit: The Unconditional Conditional Withholder?

Funny thing: at this month's Los Angeles Revit Users Group someone mentioned how absurd it is (OK it was me) that there can be found functionality in some Revits that aren't in others... Well Steve Stafford with the help of David Baldacchino has posted a nifty find of some hidden functionality that IS actually there. See Steve's conditional post and David's additional post.
