If you head over to the Samba project, this allows you to configure file shares across your network, which allows your clients to have their home drive and other network shares mapped to the machine. So, when you save a document, it actually saves it on the server and so can be access from another machine when you logon to it. Although it's aimed more at using Windows clients, you can still do it with Linux clients to have some functionality of mapping the home directory from the server.

There is a ton of documentation on the Samab site, and maybe the K12 LTSP project may worth looking at as they provide very similar stuff to what you're after.

Thanks. I will try make that!
