Tried it on my Mac and it works quite well! I have a couple of requests:

1. Can you create the liveViz particle exercise as a separate file within a new 'liveViz' folder? Also, restore the existing ccs_server example
2. Can you add a README explaining how to run this, and can you include a screenshot of what liveViz would look like if run correctly?
3. Can you update the documentation with a new page that briefly describes liveViz and how to run it? As a side note, the goal of liveViz is to visually show the effects of migration and load balancing, so you should try adding command-line options like +balancer GreedyLB and +balancer RefineLB to see the effects of those load balancing strategies on the particles.

Hopefully made all the changes for an initial merge. Will fiddle around with the balancers for the example. I also ended up implementing a poll mode with a pretty straightforward queue system, so do let me know if everything looks ok or whether there's something I need to change.
