Um, but that's why even Solaris's openat(2) proposal doesn't expose
streams or extended attributes as "normal files". The answer is that
you can't just expose named streams or extended attributes as "normal
files" without screwing yourself.
Reiser4 does I believe...

I was not talking about Solaris/UFS. NTFS has named streams and extended
attributes and both are stored as separate attribute records inside the
same inode as the data attribute. (A bit simplified as multiple inodes
can be in use for one "file" when an inode's attributes become large than
an inode - in that case attributes are either moved whole to a new inode
and/or are chopped up in bits and each bit goes to a different inode.)

True, but perhaps in this case it's time for POSIX to move, the things
in filesystems, and which are used as filesystems have changed a bunch.
It would be nice to have a neutral standard rather than adopting
existing extended implementations, just because the politics of it are
that everyone but MS would hate NTFS, MS would hate any of the existing
others, and a new standard would have the same impact on everyone and
therefore might be viable. Not a quick fix, however, standards take a
LONG time.
