Got a visit from the cable TV salesman pushing digital cable and cable Internet. Stumped him immediately: "Do you allow servers?" Guy went off for a while to call in the question, and came back with a suggestion that I call someone specific at his office. I'll call tomorrow. Apparently, they do offer a business service with static IP. Since my current DSL provider doesn't, that may be reason to switch, if the cost isn't exorbitant.
