A motivtaed and intererested individual might want to
investigate www.archive.org for hosting opportunites.
They are very generous with their space. My
understanding is that they will allow anyone to upload
anything (sound, image, whatever) for free, forever,
the only "string" being that it be uploaded under a
creative commons license (of the uploaders choosing).
If this sounds too good to be true, check it out. I
may be able to be of service to this list in this
regard in a few months, as I may be involved in a
moving image project with them but there's nothing
stopping anyone from looking into it now...
