I've seen a number of these built as proprietary solutions using ZooKeeper. It would be great to see something open sourced. HBase/ZK seems like a good fit. You might also consider ZooKeeper/BookKeeper.

Currently I'm planning to implement my own system based on HBase and
ZooKeeper. If there isn't any free software solution by now, then I'd propose
at work to develop our solution as Free Software.

Thank you for any hints,
