Its not worth it.. The only way right now you can get into the ISP business, is to be a "virtual ISP". Basicly outsource everything!! and just colocate your web server with who ever you get to do you dialup with.. Then maybe if you are successfull you setup your own ISP then.

There's also always space in the business for a web presence provider. Where you only offer web space.. Then just offer space for cheap..
