I'm sure I could think about this more and figure it out, but its a lazy Saturday. If you aren't comfortable at the command line to the point where you need something like cPanel then whats the point of using a VPS over shared hosting? I pay something ridiculous like $8 a month for dreamhost just to host a few sites I don't want to deal with. (Note I also run a VPS for other things - but I maintain it myself from a prompt)
