Thanks for the comments, this was an interesting exchange (between Regularuser and ChessControl).
The numbers here are pretty accurate.
There are a couple of costs you left out. I personally won't run the hardware (we'll have more to say about this shortly). This is a service which requires a profit. I also won't personally take orders and provide the first line of service to users. That will be done by ChessBase and Convekta and that also requires a profit.
I'm hoping for a utilization of 33.3%, not 16.7% as you give. Hopefully, this isn't a case where projections are driven by wishes instead of reality. There will be some possibilities for offline processing, which would be entered into a queue and performed when CPU time is available. (Convekta is interested in this but ChessBase for the time being is not.) There may also be different rates for different times (although in the interest of simplicity this is not the current plan).
Down the road, the servers will be replaced by computers with FPGA accelerators. For this and other reasons, I don't like the idea of using generic hardware providers.
The main short-term issue is that everybody who uses this service must have a first-class experience, and this means starting slow. We've had several plans to launch already, which always involved accepting hundreds of users at once. I got cold feet at the last minute, and I'm glad that I did. There would have been too many problems and no time to satisfy them. The same issue applies to renting single logical cores.
Anyway, it's going to be fun and I have no idea what will happen. The upside is really nice. Worst case: we'll just have a handful of wealthy users.
