Storage is not the major choke point - bandwidth is. Lossless
compression technology will find its best application in network
transmission of material: speeding long distance collaboration and
delivery.
I agree with Walt vis a vis being conservative with formats for
archiving. PCM bwav (broadcast wav) on well-stored commodity media
(CD-R, DVD-R) with periodic re-copying is looking pretty future-proof
at this point.
