Thanks for the suggestion regarding Atom or other ULV processors, but I think this is the easy way out and circumvents what could be a very meaningful development in LTSP. We can get about 3-4 arm or mips thin clients for the price of one atom based client. Moreover, I am trying to do this as way to redress the apparent technology gap here in the developing world. It should be pretty easy to build a thin client image for ARM (particularly as linux already runs on ARM). I understand that MIPS has some support, but it is not as good as ARM.
Anyway, I was actually hoping to find if anyone knew if there was work under way to get LTSP working on these architectures. Does anyone else have any ideas? I suppose I could start by compiling my own, but I would like to see this make it into the standard development chain.
