Fascinating. Seems to me that DNA as a storage medium would have to be "kept alive"--whatever keeping alive DNA separated from a heart (and blood) central nervous system, etc., would look like. The whole field of gene manipulation is already a scary topic for me..with the potential for cloning, gene splicing, etc. This seems like a whole new dimension to that same ethical quandary. Going to have to think about this one awhile... Thanks for the interesting topic.
