It is a nice presentation and that is good to get together and present the works. From my experience such presentation is one-way mostly, the observer are passive participants. I like more interaction, for such event, I prefer a gathering like workshops, so people interact, they still present but chat and stop and discuss then the ideas can be discussed in details and the decision for some changes done. I found it always more effective of course if the number of participants too large then it is not possible, but if not then this is the best and very productive :)
