10. ALAR 2005 - E2 Architecture - Minh Vu 10 E2 Project Using eclipse ideas:  Agent  instance of eclipse platform.  Capability  plugin. Add features:  Dynamic add/remove/connect plugins.  More flexible on integrate plugins.  Facilitate communicate intra-platform between plugins Performance improvement:  Skim reading interface.  Share JVM.  Smaller foot print.
