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 ;)

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.
