Introduction: the NeSSI generations
Marketing
• Publications– increasing number of articles and reviews of NeSSI
• Media pack– media pack prepared
• Wiki– we’re in the world’s encyclopaedia
• History– we’re so old that we have an auto-biography
• And our home library is still at the CPAC site

The big issues
Gen I: fluid handling• Demonstrating the value proposition
Generation II: networked connectivity• Commonality of network design / avoiding bus wars• Establishing and maintaining comms standard• Establishing and maintaining a data standard
Topics for this evening’s workshop
Generation III: microanalytical systems• Getting the momentum of an initiative
