sorry!  I should have explicitly said I'm worried about stability,
not pure downward load-bearing-ness.  I mean, the floor is level,
but not microscopically, and if someone leans on a rack, I'd like 
not to have the whole machineroom suddenly shear ;)

presumably the grid (stringers) do most of the lateral stabilization,
but they're not all that hefty themselves.  obviously with all/most
tiles in place, the mesh is MUCH stiffer.

but I guess that's the real point: it's a question of how much lateral
thrust might possibly be encountered, and how well, say, a tile-less 
mesh of stringers+feet would handle it.

thanks, mark hahn.
