I need a solution like dropbox for computers in our lab where students have access to their files. We created an account for our lab on dropbox and so there's a folder now synced on all computers for each student. Problem is students can see and **edit** other students' work.

How can we protect these folders? We could make every student have a dropbox account, login when they get here (*perfectly acceptable*), logout when they leave (*again perfectly acceptable*) and delete their dropbox folder so the next student can login to their dropbox account. I ***know*** this is going to be prone to mistakes and conflicts though.

Sugarsync seems to have an amazing solution for my needs. A pure cloud drive. When you close the Sugarsync application, your drive disappears, because it was always in the cloud. Problem with it is you ***can't log off***! Surprising... but I don't know how yet. Seems like you have to uninstall the app to change accounts? There must be a registry entry or file with the information.

***UPDATE***: I found out you type `control` `shift` `R` to uninstall Sugarsync. It doesn't really uninstall though, it just quits and when you run it again it asks for new account or user/password. Perfect! Except then you have to say no to upgrading, name the computer, etc... Not very nice, but it'll work if there are no other solutions.

***UPDATE 2***: I should've noted we have Macs and PCs.
