I read up on jails and I am impressed, I had a vague idea about them but 
they are apparently a lot more powerful than I thought. This will get 
some use from me in the future when I'm setting up real servers.

However, for what I'm currently doing, I want to stick with a bunch of 
VirtualBox VMs so I can simulate database failover by killing the VM in 
rude way, dynamically throw another "machine" into the mix, etc.

Thanks!
