if they can keep support costs down, they just might be making reasonable money on the deal. This is pretty close what I charge for my larger accounts (I mean, proportionally. I charge a $4/month per-account fee, then $1/month for every 64MiB of ram) but with my abuse/support costs, removing that $4/month surcharge would kill me. But I can see how someone with better automation and/or lower helpdesk/abuse costs than I have could pull it off.
