Status update:

have been unsuccessful at getting anything to work on approach 3 and 4.  Did not try 2.  On 3, I don’t understand why that won’t work.  But when I changed sub folders, autoloader would not incrementally load them.  

i have been successful on approach 1 using a slightly narrower glob pattern so as to avoid the really ugly large unsplittable files.  

im still wondering if 3 or 4 are possible?
