no offense, but the price for this is way too high. You might want to lower your prices, or else you're gonna get little to no sales. Even worse, someone is probably going to come along, and make a open source version that is better than yours, and you're gonna be out of business.
Don't believe me? This is exactly what happened with hdminer.

I think for someone looking to start up a public and reliable pool, $199 is a relatively small amount to pay. I think a good anti-DDOS server costs in the neighborhood of $1000-$1500 monthly. $199, or even $99, opens it up to even the average enthusiast who might think "hey, I'd like to start up my own pool and see what happens." The big issue is in the code being untested in a large pool. I would encourage Kris to start his own pool based off of this code set to prove the concept out and show everyone that it does, in fact, work.
Sure, he could go lower than that, but at that point, you would have too many people buying, and he would lose his source code to piraters/copyright infringers. With only a handful of buyers, it is less likely to get out "into the wild".
