Ext4 filesystem support for MacOSX

[erick2red]

i've been searching around if already someone did a kexts in order to add MacOSX support ext4 new filesystems available for linux, and nothing found, i would like to make a try, or at least start the digging for it.
Actually i'm using ext4 on my root linux partition, and ext3 (too lazy, too slow) on my home partition so i can read it from MacOSX, but i would love to move all my linux partition to ext4 which really improve the experience.
so the theme is open, i'm hearing any suggestion before start developing.....
