First of all, Microsoft Office running on a bunch of Windows-emulating
services (would CSRSS.EXE be one of these?) is not "native". In a
similar fashion, a Unix app running on cygwin and using X for its
display is not really "native" either. I follow the Wine project a
little, and the things they have to do in order to run Windows
binaries lift Wine a large step above being a toolkit.
Second, I don't understand why this is a useful goal. Programs such
as Emacs have had difficulty mixing well with NT (e.g. NT's primitive
process model; okay "different" process model); why should the
converse not be true? And if you follow that approach to NT/Unix
integration, why not just drop Samba, implement the Win32 API (Wine!)
the NT system traps and suggest that Microsoft recompile SRV.EXE, et
al. on Unix?
Which brings me to my next point. Office and such rely on a number of
chunks of software, updated versions of which these applications
frequently install themselves. One example that springs to mind is
the COM/OLE libaries. Do you reimplement those, or use Microsoft's

One example of Samba meeting the underlying OS with some unease is in
the area of utmp/wtmp handling. As I recall, almost every Unix is/was
a special case.

I'm pretty sure that ext2fs on Linux can store UTF-8 filenames; is
UTF-8 just "not good enough" (both in this case and in general)? Can
other Unix filesystems handle UTF-8 in a useful fashion?

I'd like some details on this; if it's been written up, an URL. I've
found it difficult to locate documentation for PAM in the past.

I hope this doesn't sound sarcastic, but is it safe to assume that
winbindd is close to a "final solution", or is there a chance of it
being abandoned in the same fashion as pam_ntdom has been?
This is a bit of a ramble. Hope some sense shines through.
