If I'm understanding your problem correctly, owncloud or similar
could do it:

I'd also strongly consider setting up a bittorrent server and
bittorrent clients if the internal network architecture allows
for it, the data is static, and there's no need for authentication
or confidentiality because of how efficient bittorrent is for
moving data.
