It's my belief that every EDEN Unit, including all at Sawston, will be tied by the net to FlaskWorks which will monitor the operation of each unit. If it detects any anomalies in the operation, the vaccine would undergo more detailed analysis, and the unit would be returned to FlaskWorks for maintenance and replaced by them.
I believe the UK took this under consideration in announcing acceptance of the hub and spoke model.
