IIRC, it takes about 50% of the network to do so. This is a waste of $100k though, as the network is only used by a small number of people, and this would be a permanent sinkhole of the money and these added servers would simply disappear after a year.

This guy/gal definitely needs something more interesting. Perhaps something meaningful, or perhaps just something insanely cool. A temporary addition to an existing worker farm is not a great idea.
