> But, IMHO, this is precisely the difference between Unix and Plan9. The important difference is that in Unix the "terminal", specially graphics terminals like X servers, have to be trusted to be in good hands - which cannot be enforced. When you look at NFS, for example, a trusted network node can totally subvert security if the trust cannot be ensured.
Plan 9 gets around all these issues by putting security where it belongs and not giving a false sense of security by means of sobscure protocols and other ineffectual means. Lucio.
