Interesting thought, but using bittorrent would require the setup of several peer sites in order to do its thing. Probably a good idea from a preservation standpoint but I would suspect not practical for many, and there are of course easier ways to support large transfer demands.
I've thought that if a need emerged for us to handle this type of media, the DAS we use for the assetstore would be just fine, as of course would a SAN or NAS arrangement, but submissions would probably need to come on removable media and be loaded by staff, and distribution would probably need to be via streaming, which I know has been discussed on this list. To me those are the indicated approaches for this issue. c On Mon, 2007-04-16 at 22:30 -0300, Afonso Comba de Araujo Neto wrote: > The problem is very intriguing and I felt like giving my 2 cents. > > I don't even think the problem is where you'll put it or how you'll > integrate such files to DSpace.
