I'd personally like to see more support for people gathering more diverse data sets. If private companies feel it is in their interest to share their data with others and contribute to scientific knowledge then this is wonderful. Obviously if your result is to be believed, you will have to share data so that someone else can attempt to replicate your analysis or compare your results with other methods. It is nice to have benchmark datasets, but there is a danger that research on "object recognition" can become research on the "caltech 101" dataset.
