As far as I can tell, there is no entirely satisfactory way to control
NT-based applications.

It's the other direction -- your machines will not accept mail.

The scyld.com machine that hosts the Beowulf mailing list is the same
one that hosts the Linux network drivers mailing lists, and thus does
not use any pre-filtering.  The mailing list messages are moderated by
hand.

Yes, used VMWare on compute nodes, with the process monitored and
controlled by the master machine.  The VMWare process is started from
the master and put on a compute/server node, but isn't moved after the
initial placement.

I would think that the CPU and communication overhead of Mosix would
limit it to support a tiny number of compute nodes.
