Callback... everything?

It would be really great if we would have more native executeDATs or callbacks for alot of components. It does not have to be everything but for example the fileInOPs or engineCOMP would profit alot by having native callbacks for the most standart events like onLoadingComplete, onError or for NDI and Spout TOP firing onConnectionLoss, onNewSource etc.

Alot of them are already possible using the InfoCHOP, but it would be great get arround that for a more tight programming.
