 10.7n.0.40 is repository2 (frisbee, pxe, and home).  10.7n.0.1 is the PIX interface.  The current PIX can only be homed on 25 VLANS, so among these it is only homed on VLAN 31.

+Absent a sophisticated "tetris-capable" Resource Manager (RM), we simply divide the physical grid into four equal quadrants, each becoming a virtual grid.  This "prototype topology" is specifically as follows.
+
+|| Physical Nodes     || vgrid  || vx =   || vy =   ||  
+|| (1,1) to (10,10)   || vgrid1 || x      || y      ||
+|| (11,1) to (20,10)  || vgrid2 || x + 10 || y      ||
+|| (1,11) to (10,20)  || vgrid3 || x      || y + 10 ||
+|| (11,11) to (20,20) || vgrid4 || x + 10 || y + 10 ||
+
+Each virtual grid addresses nodes from (1,1) to (10,10).  It is important to note that all the mechanisms for implementing four vgrids can be extended to support larger quantities of simultaneous experiments without additional hardware.  The simple 'vx = x + 10' style of mapping virtual to physical nodes can be modified to support arbitrary non-overlapping mappings without significant redesign of the system.
