Gotta say I am seriously looking into hosted as a customer for my start up. As many know here I am a hardware guy but the initial cost is much easier for me to manage and I can use the money else where for now. I don't know if I would want to sell it as I am still waiting on the infrastructure we were promised years ago. Who knows if the experience is good from the customer side it might be worth looking into selling voip/hardware services in the near future. Look at how many home users have bundled there services with the cable companies.
