The real issue is that Septemberfest was originally set up to allow interaction between producers and consumers. The amount of interaction last year relates to the same amount you get in a city centre bar at11pm on a Saturday night.
And before we dare suggest that the producers run this event themselves, Bord Bia would be on good terms with the OPW who have no issue giving "them" the land to use.
And thats not without insurance, organising tons of volunteers, transport etc.
Shame
