Yes i heard about VPN but in some cases in a big environnement you
cannot play with networks and firewalls as you like.
And there is a lot of remote sites to discuss, create VPN trought all
theses remote sites is to complicated to maintain.

yes i need to find a plugin like djigzo but djigzo is too heavy product
(postgrey, web server... ) that requires too much components to
implement
