To be honest, I wouldn't be interested. The reason is that datacenters experience huge economies of scale allowing colocation costs for servers to be as low as possible. Their infrastructure is redundant and built for high performance and low latency.
If you want to profit from this, you would need datacenter experience and resell colocation with management as a service.
All true though I am not sure of the point. The typical server is neither going to use the kind of equipment used for mining and probably not going to have high-mem for coins like LTC; they won't permit use of cards, and I'm not thinking BTC (of course) excepting someone wants to run some ASICS. Then there is the fact that a datacenter certainly charges quite a bit, especially for machine-intensive work, electrically expensive work, etc. (It's a buddy that has the server and admin experience btw). I was thinking of those who like to do mining but have to use their electricity.
So I'm thinking that with creativity there is going to be a coin or two (or a hundred) that would be worth mining where there is free E. Thanks for the input however.
