I will spend a little time getting this done as a patch to magnum-jumbo.  I will rip out almost all modified formats, and simply change the null pointer for get_source to point to fmt_default_get_source.  Removing the modifications to all the formats should make the patch a little more stable against changes, but likely this patch will be a PITA, and I am hopeful that we can get this into a jumbo quickly.  

NOTE, this modification greatly improves the scalability of JtR.  Yes, we may need to smooth out  a bug or 2, but this simple modification does reduce the memory footprint by 40% or more.  Also, I have seen speed improvements, on huge data set's and Magnum was mentioning improvements in self test speeds.
