The more you mix business and government with IT the less fun it will be. Perhaps technology being more widespread gives a similar effect. IT Geeks once were like modern day wizards wielding their craft across the land. We were unique, somewhat scary, and to most, unnecessary. Now IT is everywhere and IT Geeks are probably more like pharmacists. Everybody needs them but they are far from impressive and it is easy enough to find one who will do an adequate job.
I have been using P90X from the same company and it is very good. P90X wants 60-90 minutes a day but the 10 minute trainer sounds more like what the poster wants to fight off weight gain.
The original post is concerned about employees not being able to use instant messaging out to the rest of the world, which implies they are actually networked to the rest of the world. The setup you describe is not that situation. A KVM switch should not be Internet Protocol connection between the isolated and non-isolated PCs you are describing [I know, it is possible to have an IP KVM switch, but if the switch is IP then you have left open an obvious attack vector should the (more directly) Internet connected PC become compromised]. The point in the army lab would be accessibility to outside information on the Internet connected PC without potential threat to sensitive data on the PC not connected to the Internet.
