Query: The QCD Equation of State in Small Systems   We present first results on finite system size corrections to the equation of
state, trace anomaly, and speed of sound for two model systems: 1) free,
massless scalar theory and 2) quenched QCD with periodic boundary conditions
(PBC). We further present work-in-progress results for quenched QCD with
Dirichlet boundary conditions.
