There are some exceptions, but I really wouldn't recommend it. http://osdir.com/ml/network.etherboot.user/2006-03/msg00006.html If you can get over the booting issue (either using TCOS or some other small OS locally on the desktop), you will then, I suspect hit another issue. 20 desktops running wirelessly as thin clients on a single 802.11g network doesn't sound nice. The network may in principal be 54Mbps but in practice you get a lot less than that, even when things work well. Where signals get weak, things get even worse. http://en.wikipedia.org/wiki/IEEE_802.11 http://en.wikipedia.org/wiki/802.11g This is just instinct, I've never tried running 20 wireless thin clients on a single access point, but I'd have grave doubts that it work well. If you get it to work well, that would be very interesting to know. My advice, such as it is, is to install Edubuntu or possibly Xubuntu on the desktops, mount /home over nfs and use LDAP or NIS for centralised authentication. If you have 300 desktops, you'll need to come up with some sort of cloning mechanism to do it quickly and some further tricks to keep them all configured. That way, you'll use the wireless for internet access and user files only. > Another thing, we were hoping to get a small iso image that could be used > in the clients instead of installing the full edubuntu desktop which also > have all the application programs that are in the edubuntu server.

When you're using thin clients, you don't install applications on the thin clients, you only install them on the server. > Can we please work gtogether in this project and please don't ask why I > don't use cables?

I haven't asked why you don't use cables but there are really good reasons why I would like to ask.
