I just caught an announcement of a new CEN Workshop that looks rather interesting from an interoperability point of view.
"The Global e-Business Interoperability Test Bed project (GITB) focuses on methodologies and architectures that support e-business standards assessment and testing activities from early stages of eBusiness standards implementation, to proof-of-concept demonstrations, to conformance and interoperability testing." - from http://www.cen.eu/cen/Sectors/Sectors/ISSS/Workshops/Pages/Testbed.aspx
The business plan is ambitious, to say the least, but even modest advance in technical terms could have significant practical benefit. I certainly see the future of interoperability standards in education being meshed with achievements of global eBusiness interoperability as well as global web standards.
