Boost::asio, Keep-alive, Boost::serialization

Boost::serialization is the ultimate solution if you want to send your objects trough a socket. I remember the old days when we were used to work with corba and similar stuff. Thanks to god this is not longer requested. This code is extending the async io server and serialize a test object. Ping messages are objects too. Generic programming is used to send as many different objects as you want. .. we are moving towards a full map reduce implementation
