This document reports about experiences made with running OGSA ByteIO working group interoperability test scenarios 
based on the ByteIO OGSA® WSRF Basic Profile Rendering 1.0 of the ByteIO Specification 1.0 as implemented by the four 
groups participating in the OGSA ByteIO Interoperability Fiesta. The four groups represented different implementation 
environments: Genesis II by the University of Virginia (UVa), UNICORE by Forschungszentrum Jülich, OGSA-DAI by EPCC, 
the University of Edinburgh (EPCC), and a clean-room implementation by Fujitsu Labs of Europe (FLE).
