Query: Fuzzy Bags and Wilson Lines   I start with an elementary observation about the pressure in the deconfined
phase of a SU(3) gauge theory without quarks. This suggests a ``fuzzy'' bag
model for the analogous pressure in QCD, with dynamical quarks. I then sketch
how the deconfined phase might be described using an effective theory of Wilson
lines. To leading order in weak coupling, the effective electric field appears
in a form familiar from the lattice theory of Banks and Ukawa.
