I am considering using TCH for some hosting. I use my own DNS server (well, actually the DNS at the excellent registrar IthacaDomains.com) for several reasons, including the experience that if I want to point anyoldserver. whatever. com somewhere I don't want to wait for someone else to take care of it.
1. Do you require that TCH host the DNS server?
2. If so, is it a problem to have something other than www. point to the web space?
