You might not want this - some apps might not work well being displayed over
X.  Also, often I have my girlfriend using my NT box at its console and I
using
it via a window manager exported to an Xterminal.  I would want to run x
forwarded apps,
she would want to use native GDI apps.

This would require a replacement GINA.  I think this is almost another
project
- would you also want to replace the task manager etc?

As above I currently do that.

Would be good too.

No it doesn't.  Take a look at the attached files.  These should be enough
to build
a user32.dll which forwards all calls to U32X4WIN.DLL (which is what you
rename user32.dll
to).  

I haven't tested this yet as my win2000 user32.dll exports functions not
defined in my user32.lib.  I guess I need to download the win2000 sdk (I
created the .def file by 'dumpbin /exports USER32.DLL | ./fixup.pl ).

can you post a link?

Hum - I like this idea (so you have the apps running native and in X at the
same time
but this will make things very complex - certainly when we start thinking
about input)

Yes, I can see a lot of wine code being sucked into this.
