[ Cloud Computing ] What is "Internal IT" ?

I guess it's my day to stir up the cc list, but here's another topic I'm wondering about... I keep hearing phrases like "behind the firewall" and "internal IT" used, primarily to support points around control of QoS (including security), and also often to claim cost advantage.

My question is whether these things really still exist?

Are enterprises not now more distributed, outsourced, leveraged, and prone to merging and splitting than before? How can anyone say their business runs behind a single firewall, or even the moral equivalent of such a thing?

Are the means of access to "enterprise" data not multiplying as computing devices and client platforms proliferate?

Are the sources of "enterprise" data not also multiplying to include externally sourced information, sensors, and all the operational data from the outsourced functions?

Are the clients connecting to "enterprise" data not also expanding for the same reasons? Is my Chumby expected to understand VPN and NAC before it can be a meaningful mini-dashboard? Is it really cost-effective to prevent employees from working at home, in starbucks, on planes, or while playing xbox?

Do most enterprise datacenters not resemble cloud datacenters to a great degree? Don't they have their own firewalls, policies and controls separate from the rest of the "enterprise"?

Is "enterprise IT vs. cloud" a useful distinction to make or not?
