There is a new conference taking place in 2009. You can find the call for paper here. Thing I find most promissing about it is: they actually try to use the quality of presentation technique for deciding on the selection of talks:

Einreichungen, die alternative, partizipativere Formate
verwenden, werden bevorzugt. Wenn die klassische Vortragsform gewählt wird, dann sind
uns auch hier unkonventionelle Stile lieber.

(Proposals with an alternative participating format will be preferred. Even if a classical style is choosen a unconventional style is preferred)

Also the type of talks they are looking for sound interesting:

Maybe we'll see us at the conference that looks behind the buzzwords.
