Speaking of unexchanged...
Besides getting the pool running smoothly and having the best algorithm for mining the right coin at a given time, I imagine that the mechanics of actually exchanging alts for btc's is going to be the biggest variable in profitability. The exchange rates are so volatile, I imagine that efficiency of getting the mined alts to an exchange and trading them for btc while they are still "hot" has to be a huge issue.
Is there any way to maximize efficiency in this area that you are not already taking advantage of, @Terk? Using multiple exchanges, automating transfers and sales of alts? Or is there no way to automate this stuff and it just has to be done by hand?
Some things always have to be done by hand but I am automating anything that is possible to automate. I have one more thing that is semi-automated and I want it to be fully automated and I'm going to work on it tonight. There is no way I could run this pool without automating as much as possible.
