The original post seems a bit unix-centric. Much of what he is complaining about comes from the nature of TCP/IP networking, Unix can only be blamed to the extent that it doesn't abstract things like ports away.
The general thrust of his post is to fix Unix so that its (ohh so well
respected!) permission model can extend across into the cloud. This will run into friction when more than one OS is involved.
That said: anything that unifies all the different kinds of virtualization as the OP wants would need to be an OS. And the only plausible candidate for an OS lingua-franca in this world is Unix.

So long live unixcentricsim?
