Maybe this is an opportunity to use machine learning to filter this stuff out? It could be done on the client side for every user connecting to the network. That way each user would have control over what comes into their machine, rather than just being an open dropbox. You could also force everything to be plaintext and just block anything encrypted or in an unrecognized file format.
