It should be doable, yes. Another alternative is to verify that the drivers you are using (specifically NIC and disk drives) are set to provide entropy (there's a driver flag for it, can't remember what it's called right now) Cheers, Muli -- Muli Ben-Yehuda http://www.mulix.org | http://mulix.livejournal.com/
