Wasn't someone of the major players looking into this stuff?
I thought I saw something about either Hynix or Micron looking into similar tech a year back. Wonder what happened to that one...
As far as Cisco's pitch - well, if people employed competent software developers and sysadmins which wrote and deployed software so it could _SHARE_ boxes than there would have been no need for their kit.
It is a matter of choice - employ competent people or pay for an idiot which allocates 4G to a VM regardless does it need it or not...
