Not really. Have a look into fhandler/proc.cc, fhandler/process.cc, etc. We can add a permisions member to struct virt_tab_t and add this as static info to every member in the list. Doesn't sound overly complicated to me (*nudge, nudge*). Changing <defunct> to a "Permission denied" when trying to open a virtual symlink may be a bit more involved, but maybe not very much.
