Wow, now as outlined above, it just rocks. :) Because the functionality would be there to take advantage of by all sorts of means, some of which have already arisen in this thread (apart from my initial suggestion) and some more are outlined below.

This could mean a lot of new features indeed: fancy envelope
controling! Imagine adding an integrated tuner or a VU meter to
ecasound once the audio-stamp would have been implemented; there would
only be the feature itself to care about because all the framework
would already be here...
