I went looking for a machine capable of this and got about halfway there
with http://www.tech-news.com/publib/pl2818.html which allows up to
248Gb memory -- near as I can tell the price for the maxed out system is
$2,546,200. Plus $3k/mo maintenance. Memory's still not quite enough,
but I'll bet it's fast. And a lot more reasonable at $1000 per Gb of
memory particularly when contrasted to the $1000 I paid for a single Mb
of memory back in 1984 or thereabouts.
