OK -- I'll put this on the back-burner with the so-called "ent:relative" patch and I'll revisit this once your "delta" attribute shows up in next or master.

At the moment I'm experimenting on a git repository with a 4.5GB checkout, and 18 months of history in 4K commits comprising 100GB (uncompressed) of blobs stored in 7 packfiles of 2GB or less. Hopefully I'll be able to say more about tweaking packing shortly.

Thanks,
