I don't think this is a good idea for "all X terminals". I for one don't want to lose the independence I have by having my X server running on my terminal. With the X server local, I never have to wory about hosts going down, network interrupts, and the like. As for general memory restrictions, the NCD19 will hold up to 8 MBytes of memory. I have never run out of memory since I upgraded to 8 MBytes. -- Daren -- Daren W.
