Here in Latin america is not cheap... at least now. :) But you have a good point. > Also, absent very careful inspection of the network code, the virtual > memory manager and other parts of the kernel, I fear you could get into a > race condition between the network code and the code that causes a page > fault.

Right now I'm thinking to try it like an experiment, only one client and one server to see exactly what you fear... and then decide to use it or not. We have aprox. 15 machines that boots through nfs-root and they don't have swap space, this machines don't work like a real workstation.... they are used to run scientific programs only.
