Virtual IP stack (as well as virtualized sysvipc with separate memory zones) can be quite useful. Can provide two solutions? - with shared memory zone (for those who want "light" version) - with separate memory zones (for people who want to keep sysvipc fully separated, i.e. one user can't exhaust all sysvipc resources and make sysvipc unusable for second user) /fjoe
