It depends on what features you know about/need ;)
Comparing with btrfs [1], with ext2/3 (and the upcoming ext4 [2], which is not
more than another patch over ext2) you can't do:
- object level data mirroring
- Subvolumes and snapshots
- fs level raid
- online fsck
- fsck 1 TB filesystem on less than a couple of days ;)
- Never run out of inodes. ext4 still (we're on 2009!) suffers from this one :(
- Online FS growth and shrinking
- FS level compression
- Online defrag (*)
- Tail packing (*)
- And much more
(*) also supported by ext4, but not ext2/3
Although many of that features are useles for devices like Freerunner, some
other would make a difference: dynamic inode allocation, tail packing, fast
and online fsck...
And reiserfs is the closest to btrfs we have on OM kernel :)
What is true is that kernel developers are making clear that ext4 is not "the
future fs", but "the interim fs until btrfs makes stable"

Yes, it's possible
