The primary difficulty is that the Library is attempting more than just live-capture of video streams. They are going for full archival quality. They're not simply saving streams to tape but but running extensive qc processes on everything and transcoding coding the material into multiple formats. Technically, the technology exists, but the Library does not have the hardware to run the software. (Unless someone knows of some efficient, off the shelf content-validation program that we don't know of...) Other problems include, yes, storage. The projected aggregation rate will outstrip, not only the Libraries current physical facilities, but all planned new facilities, by 2013 (at which point we will be looking at 250PB of storage.) The rate of growth will continue to increase from there. Unless tape technology improves at an exponential rate, this seem unavoidable.
