i think reiser has a lot of cool ideas, but i haven't tried it.
even with reiser you need to move away from the POSIX API to make a huge
dent in the scalability of maildirs... you need to start amortizing
multiple file operations per system call for one thing. (and there is a
sys_reiser or something proposed for this, but i haven't looked at it).
but that still doesn't help all the dcache and inode cache overhead in the
kernel... and backup systems will still continue to blow chunks when
presented with 100Ms of inodes...
