Well, I'm all for it, but let's be honest, my opinion is pretty much worthless here
Maybe you should get a couple of months down the road with the Windows SecWiz first? No doubt that will throw up a few questions that will improve things.
Then if you had Linux guys to assist (or if you are good to go in that department), at that stage you could look at adding to the SecWiz. It just sounds like more work to me, and there was enough setting up the Windows department. But if you've got the energy...
Maybe we should post a new PC out to MC for him to load Linux on and play with, I don't think he's fully occupied at the moment.
Me, I'm a tiny bit busy. Just moved, with all the problems in that. Then the DSL at my new place started playing up, and I've been through 3 routers in 4 days trying to fix it.
