(I'm looking forward to the IBM guy's slide show getting on 
the LUGOD web site.)

His comments were mostly about virtual mainframe OS 
partitions for Linux, but he did make a very brief 
reference to how it was the same for NT. And I've heard it 
from senior IBM mainframe sysadmns.

I'm not saying that NT would run natively on IBM mainframe
hardware.

If an IBM mainframe can run a Linux kernel that was written 
for x86 in a virtual mainframe OS partition (or whatever 
they call it), why couldn't it also run an NT kernel for 
x86?

Wouldn't their abstraction layer be basically the same for
any OS on x86?
