I think that it is a natural progression in osm to include information like this, and so to (eventually) make ENC maps freely available. The certification may be a problem though. I do not know enough about it to comment.
I am not sure if the majority of people would want this information in the planet downloads, using the same reasoning as the SRTM data. So what is the best way/place to store this data? How could underwater relief data be collected? Data feeds from vessel sonar? Google earth now goes underwater! I wonder how long until their maps also have an underwater relief.
