Cris, I am in the initial stages of talking to a company to do some Knowledge Management (SigmaLink) work for their internal use. I made a proposal to provide a similar service to their clients. If something like that occurs, then I can setup a large MPP cluster with a lot of NAS to convert the clients Information to Knowledge. If we get 10 clients, at first, I can setup the standard Information Warehouse with data access softwares. Later, I can tinker with software and architecture to create an expert system. After that, I have an architecture, I have been noodling for 5 years, I am going to try. No promises, but this just might work.
