Very interesting.

I note that the entire article uses "Itanium" rather than (ISTR)
their preferred "Itanic". If PSI/HP win, we may have to stand
around and cheer for the magnificent success of the Itanium.

The PSI system sounds pretty incredible. I infer that it is a layer of code
that emulates an IBM mainframe instruction set on Itanium. I know nothing
about mainframes but vaguely recall that there is a supervisor that loads
VMs ... I guess the PSI system replaces the supervisor and executes the VM
as interpreted code - amazing.

Your point (correct me if I'm wrong) is that, first, the PSI system won't
be that cheap, and second, it wouldn't matter if it were free because the
user of the PSI system would have to pay large software fees to IBM - too
large for much market penetration.

Yet there are lots of companies using IBM hardware and software. Wouldn't
the PSI system be aimed to selling boxes to those companies when they
upgrade their hardware? Particularly moving from 32 to 64 bit?
