Hi Guys,

Thanks for the reply.

When Intel first announced this memory (years ago now) I realized right away it's potential as an object database for
Smalltalk.  The OS would need to be changed to assign it to a given userId or program.  The Smalltalk VM would need to
recognize it as a special object memory that contained persistent objects and deal with it properly.  I don't think the
change to the OS or the VM should be a very big deal.

I hadn't heard much about the memory a while.  Searching now I see that 256GB goes for about $1900 and 512GB for $9000,
not cheap.  If the prices come down and the size goes up, it would be a great object database with all the ease of
accessing the data (objects) via Smalltalk.
