One very important observation and then a question.

First, and this is VERY IMPORTANT: If you copy ALL the files in the initial installation to new directories, then after an indeterminate amount of time ALL of your instances will be doing the exact same work. Instead, only copy client.exe client.cfg and key.pub .

Now the question: How do you make the instances start at a higher priority? I'm running BOINC to soak up the extra cycles, but I want Eon to dominate when it has work.
