When we say dreambox card sharing server we mean that:

1.a Dreambox as a server and NOT a pc e.g. :

2.One smartcard reader is connected to the dreambox and there is a sharing protocol is installed on it like NewCS or.. and on dreambox clients there are emulators installed!
AND Can we install linux on the pc ? so it will work like the dreambox ?

Am i right?

Can someone please talk little more about this?
