This issue really is not matter of filesystem, but of the architecture.
I wrote support for large files in ext2, hopefully it should make it soon
into 2.1.9x. Only for 64bit platforms though. If you want to convert all
variables in the kernel to long long on 32bit machines, you'd get
unbelievably bad performance.
So ext2 has been extended to support large files, only people have to use
proper hardware for what they want to do. If you need large files, you
probably should think about buying an UltraSPARC or Alpha box, as even if
e.g. file limit are increased on 32bit boxes, you'd have problems with
mmaping those large files and in several other places as well.

Cheers,
Jakub
