Google has quietly increased our CU IdentiKey "Google Drive" accounts from 30GB to 10TB. So instead of Dropbox which only allows for ~2-4GB for free accounts, you may want to migrate over to Google Drive for your online/cloud syncing services. The only "catch" is that you'd have to use storgae space that you also have locally. So most users will only be able to use 1-4TB anyway. Although 6TB drives are now also coming down in price.
If you or your group would like to know more about Google Drive and how it works with your CU IdentiKey account, let Tara or I know by emailing us at firstname.lastname@example.org
