There are lots of things to do... but obviously it ought to hit 10M nodes per second. Whether that is 10x faster than my normal search on a single quad is very doubtful. But I don't think that hoping for 50% efficiency is out of line... which means an effective speed of 5M. And this is based on the current cluster. Another 8 quad xeons are due in this Summer, for a total of 18. That just might really hit 10M useful nodes per second. But lots of things are left to play with, like shared vs local transposition tables, carefully scheduling positions on nodes that have seen them before, etc...
