I feel the dual uid approach is much more practical for networking also.
Linux iptables and all platforms with ipfw have the possibility to filter
network traffic based on the uid of I think the socket creator.
I've used this approach for a static networking POLP design in cduck, and
on some other projects also. If you pass connected or listeneing sockets
between
uid's you can avoid having to use the ptraceing stuff, and use a common
mechanism for both file and networking access.
