Strict self-refer​ence for a reentrant vi

Question

OK, I have the following scenario.
I have a background process which takes a reference of a buffer VI and auto-updates the data.  To do this I need to pass it a strct VI reference so that it can call the VIs associated with the references.
Up until now we've maintained several buffer VIs for several instances but I wanted to make a single re-entrant VI work and thus eliminate this overhead but I ran into a small problem.
I need to get a strict reference to my reentrant clone.  I can't go via "Open VI Reference" because this allocates a new clone and I can't cast a simple VI reference to the required strict type via "cast to more specific class".
How do I go about this?
I'm using LV 2011 SP1.

Type cast doesn't work.  I cannot wire a strict reference to the middle terminal of the type cast function.  unusually enough, flattening to string and back to strict type doesn't give a broken wire, but also doesn't work.
Using the clone name to open a reference doesn't work either.  At least it dodn't for me.  I was hoping that would work, but apparently not.
I have used a workaround where i open a reentrant strict typed reference (Open VI reference) and then pass this reference to the various places I want to access the buffer.  Seems not ideal, but it works fine.
Regarding use case:  I'm making changes to existing code and ti utilises a backgground process which registers strict vi references to call them whenever new data is ready.  It's not how I would ideally implement the code myself but as I said, it's making modifications to existing code so I can't just throw the rest overboard.....
