Good ext2/3 FS driver for win32 systems

I ran into this windows IFS driver for ext2 filesystems today, it can read and write the most important parts of ext2/3, and makes the linux filesystems available as regular windows drives. You can even use them to store large files, so you no longer need ntfs for that, and can share your movies/iso’s/mp3’s between OS’s without having to resort to crappy vfat/fat filesystems.
I’ve played around with it for a bit, and it seems to work very well.
