I just want to do packet spanning, I don't need the guaranteed part of
TCP.

Also, how would I tell what the maximum size is for transmitting over a
DatagramConnector?

Thanks,
Michael

As soon as you start implementing guaranteed delivery and packet
spanning with UDP, you might want to take a serious look at TCP again.
It's a great deal of work to implement and if a re-delivery is required,
it will often be slower then TCP. Basically, the advantages of UDP are
lost quickly once the packets get loaded down with extras needed for
custom protocols. This is why most UDP systems are based on a
fire-and-forget mentality (like video streaming or FPS games).

If you have to use UDP for some other reason, completely ignore me :). 
Sadly, I'm still getting my head around MINA and so I don't have any
specific implementation advice. Good luck!

Can you give me some clues as to how to implement this? I realize that
portions of messages could get lost, so, how would you recommend
implementing a 'best effort' type of service where large messages are
split and sent, then reassembled if all of them make it, and dropped
after some time if all of them don't...

Would this be a candidate for an IoFilter?

Also, Niklas mentioned MINA 0.9, is that a release somewhere or is that
what is in HEAD?

Thanks,
Michael
