How would you handle scrollbar sizing with virtual events?  The widget 
needs to know how many entries are in the tree without having any of the 
actual data.  Providing "empty" data doesn't really solve the problem 
considering datasets on the order of 10e7.  (e.g. number gates on a chip)

This is a somewhat rhetorical question, because:

This may be an area I can work on once the initial implementation is 
available.
