TomP2P

TomP2P is a P2P-based high performance key-value pair storage library. Each peer has a table (either disk-based or memory-based) to store its values. A single value can be queried or updated with a secondary key. The underlying communication framework uses Java NIO to handle many concurrent connections.

            Release Notes: Better timeout handling; uses Peer.setFutureTimeout() to set a timeout for any future object. Fixes in tracker code and peer exchange. DistributedHashHashMap.parallelRequests() is exposed (was DistributedHashHashMap.loop()); there is an example in TestDHT.testCompareAndPut() of how to use it. There is a flag to enforce UDP or TCP for RPC calls. Updated to the latest Netty to fix an issue with Android.
