Certainly you can get the NFS functionality required, (if you want), but most people want to use things like the single name space, display manager capabilities and etc, even on the nodes which are physically far away from each other. This can, of course be done using internets. And please don't tell me you don't like it cause it is different; how many products have you ever developed in which you made absolutely no design decisions to tradeoff commonality for functionality? And ether bridge is something like 3 commands and no configuration files to edit. (One could argue that it is easier than setting up NFS on a Sun.) And the product does not exclude using NFS between your suns and vaxen that you have connected to your ether. Or between your xyz machines and apollos on a ring, ether, t1 or etc. On the subject of mapping files; perhaps the compilers/loaders could be modified to recognize when to map, and when to handle the object as a byte stream; I'm not sure and am in the process of asking someone. However, to say that apollo is the only company that has this particular problem is patently untrue; it turns out that there are a few of computer manufacturers that map files into the address space (why? because it's a good idea! check out mach from cmu), and it turns out that they have the same NFS worries. ...uw-beaver david m. chinn !apcisea apollo computer inc !chinn bellevue sales office (206) 453-5544 bellevue, washington ================================================================================ Opinions?
