Here a couple you might want to look at if you want to still use Mini's - I don't own all the stuff to do this and I play so seldom these days I'm not sure I will but I want to:

I also suppose if you were to place your TV in a box facing up (if it were flat screen) you could just use the setup Mid mentioned although I have no idea how bad it would be for your players to set minis on. I imagine it would NOT be good for the screen but perhaps if the minis were made out of nerf it would be ok
And one last little thing Torstan might enjoy - I found this shot of a VTT being used by someone at En world. The user has a few shots of his own set up as well.
edit: Oh, and people who watch TV or play around with their phones too much - I just kill them off so they can go home, screw that.
