Using Mina to perform serialization with DataInput DataOutput

[David Alves]

Hi All

	I'm developing a massive cluster application that uses Hadoop RPC  
mechanism to communicate.
	Due to throughput issues I'd like to change parts of the  
communication to async mode and I thought of MINA.
	All message objects implement the Writable interface meaning they can  
write/read themselves from a DataOutput/DataInput.
	What do you think is the best strategy for implementing the  
ProtocolCodecFactory/Encoder/Decoder that would have the least array  
duplication/creation?
	I thought one of the best options would be to build an adapter  
between IoBuffer and DataInput/DataOuput since the methods are really  
quite the same.
	What do you suggest? is this the best approach? if so should I  
duplicate a class like SimpleBufferAllocator?
