This sounds like a good classification - perhaps Frank or others have more 
thoughts on this,

My personal feeling is that if we can open every supported format that the 
particular OGR/GDAL on the users machine was compiled with it would be first 
prize.

In the few minutes I had to look at your list you classification seemed right 
to me. Does this imply we will need to create a programmatic master list for 
QGIS to read and associate with GDAL formats? Perhaps indicating wich category 
the format fits into would be something Frank would consider adding to the next 
iteration of GDAL/OGR so that we always have a current classification list 
regardless of which >= current  version of gdal the user has.

I'm really looking forward to your patch!
