Amen. Linux is currently having a seriously hard time getting C/R working properly, just because of the issues you mention. The second you mix in non-local resources, things get pear-shaped. Unfortunately, even if it does work, it will probably not have the kind of nice Plan 9-ish semantics I can envision it having.
