What about the Conflicker worm? Possible host/source in that DC?

What if this is actually, say, that they found the host/source of the April 1 worm we all laughed at two days ago?

Uhm... okay. So please demonstrate how else they could do it without calling out the company and product by name?

"The next product version of the Operating System that the government agencies run, hereafter referred to in this document as Company M, product to be referred to as Product V?"

XP's only natural upgrade path is Vista. To say that they are not upgrading is to explicitly stop purchases or installs of Vista.

This isn't singling out a company or product. It is an IT department simply stating, in a governmental bureaucratic setting, that they are not confident in the upgrade-ability of the software.
