WAILworks

• Summary
• WAILworks is the critical infrastructure for
  running
• experiments in WAIL (unique capability)
• Design and development of each component is
• on track for Summer 03 completion (Phase 1)
• Future
• External access
• More GUI, visualization
• Adapting aspects of WAILworks for operational
  use
