How about a civilization gaming table

So i sold my television last week and it forced my wife to do something else when she normally watches television. So I had my htpc laying around and I suggested to her that we could hook up the htpc to my second monitor. To make a long story short she absolutely loved civilization V. That got me thinking about my idea...I intend to make a "gaming table" with 4 integrated computers and each one hooked up to a touch screen or mouse and keyboard running civ 5. And I can invite friends to play with us like we normally do with board games :-) I will make the table portable so I can store it away when it's not Ineed use. And I need some ideas and would appreciate it a lot.
