[CentOS] School cloud solution

> I manage a student file server and i would like to add cloud access to 
> it.  Basically i would like our students to have access to the same 
> files at home that they have at school.  This would allow them to start 
> an asignment at home, finish it at school, and print it off without 
> having to worry about losing their usb drive.  I want it housed on our 
> servers for backups and ease of access for our teachers when necessary.
