Ah. :)

CMFDVFTI (say that ten times fast, would'ya) is what powers the "display"  
menu in Plone 2.1. Basically, we needed a per-type way of storing a  
vocabulary of available view templates (e.g. folder listing, tabular view,  
photoalbum view for folders) and the default template. This is simply a  
"lines" property + a string property. There's also some code in  
browserdefault.py that looks this up for a type (by delegating to the FTI)  
and stores the user's per-instance selection as a property on the object.

If there is a better way of managing these things in the FTI, we may be  
able to change CMFDVFTI (doubtful before Plone 2.1.2, though!) to make use  
of it. This would likely also require an appropriate migration.
