Hi Phil,

main goal is to create a volunteer computing system/framework like
BOINC, where nodes will be able to communicate witch each other.  As you
probably know, the main problem in those kind of environments is that
nodes are not always available, have different computation power, can
give false results, etc.
Load balancing and object migration will be very helpful. However charm
++ doesn't support dynamically added nodes, right?
