The only benefit with saying you give unlimited bandwidth is that lets say you only have a 5GB bandwidth plan and this is used up in the first 2 days, your site will go down and just display a message ' this site has exceeded its monthly bandwith allowance' and will remain like this until your next billing cycle or you pay to increase your BW allowance, but with unlimited your site will remain up no matter how much BW you use, but the fact is the host has to pay for the BW.
so lets say you pay $100 a month for a server and offer unlimited plans for $10 a month, then technically someone can take out a $10 plan and use up all the server resources.
I found a better way was to give clients a set allowance and then charge an overage fee for anything over the allowance (we had ours set at £2 a GB). This means their site still remains up, we made sure we has warnings set up so clients got a warning when their space or bandwidth reached 60% and then every 5% thereafter.
