We can wait a few months. Our students are rural medical doctors. We have too many students, and many in rural areas and in the rainforest were they won't have internet acess most of the time. Sync is important so that they may have offline access. Too many GBs of data for a single website. Videos and such. Fortunately, monthly they go to town or meet a coleage or tutor. Using bit torrent sync they could get updated material in this meeting. Even with poor Internet connection, for later offline use.
