I knew that work had begun under the old project, but I did not know if
any of that work had made it out the door.  It sounded like it would be a
major effort when discussed in terms of adding it to the Mosix project.

Understood.

I personally am not in any hurry.  I knew dnetc would not work because of
shared memory.  I  knew that there was some work that was either being
done or had been done on the old project, but I was unsure if anything 
made it out the door.  I don't blame you for wanting to wait
until the VM settles down.  It was apparent that the SGI XFS engineers
were not too happy when the VM switch took place in the 2.4
series.  It appears they've since worked out whatever issues they might
have had with the new VM.  

Anyway, dnetc is often asked (this is the first I've seen on the
list) about in terms of an app for mosix or OpenMosix.  Thank-you for the
clarification. 

Cheers,

Sean...
