Mathematica 4.1 comes with the Graphics`InequalityGraphics` package that 
can do just that. The only problem is that the region you gave is 
unbounded. if you add some bounding conditions you canuse the 
InequalityPlot3D function as follows:


   x<=y+z && y<=x+z && z<=x+y&&-5<=x<=5&&-5<=y<=5,{x}, {y}, {z}]
