USB1.1 is 12 megabit ... which would easily support over 100 modems. Depends on buffering and efficiency, I suppose. But really, if you were looking at more than about 20 modems, it might be cheaper to licence some one's winmodem implementation and hire a developer to make the winmodem go against either a PRI or a VOIP connection. Modern processors should be able to handle 20 to 50 modems if well programmed.
