I start with an elementary observation about the pressure in the deconfinedphase of a SU(3) gauge theory without quarks. This suggests a ``fuzzy'' bagmodel for the analogous pressure in QCD, with dynamical quarks. I then sketchhow the deconfined phase might be described using an effective theory of Wilsonlines. To leading order in weak coupling, the effective electric field appearsin a form familiar from the lattice theory of Banks and Ukawa.Comment: 9 pages, 2 figures, PTPTeX. Based upon a talk given at Yukawa International Seminar (YKIS) 2006, ``New Frontiers in QCD -- Exotic Hadrons and Hadronic Matter'
