  We have considered the physics opportunities of future lepton-hadron
colliders and how these opportunities might be realized in a possible polarized
eRHIC facility and an e-p collider as part of a staged or final version VLHC.
We evaluated the physics priorities based on experience at HERA and, using
simulated data for e-p collisions with sqrt(s) > 1 TeV, showed how detector
designs would be impacted by the physics.
