Currently only on mouseover, though this will change in 3.1 with the detailed 
list view.

well, I can't see an advantage either because 
sizeof(KFileMetaInfo)==sizeof(KFileMetaInfo*), so no advantage in size. So as 
long as the info is empty, there is no difference at all. When info is 
written into the object (either by setMetaInfo() or by metaInfo()) your 
version needs space for an additional pointer as well as the internal memory 
that malloc needs for it, so it's slightly more.
And in the small tutorial about KFMI that I plan to write, I wanted to add a 
note that you usually never need to have pointers to KFMI objects... ;)
