While I agree that it's a good idea to start with some limits, with a business model like this (few customers, mucho $$/customer), it's probably better to let the first few customers dictate what to start out with. Of course the early product can't be everything to everyone, but it can be everything to one client! Then it's a base to build off of, finding the next client with similar needs and adding the diff to the product base. This way, as the diversity of customers grows, the product will grow with the business and open new opportunities. Having said that, I'm curious to know what you think your first customers will be like (size, industry, etc).
