Also compute the error recovery and lost packet detection and recovery
issues in terms of buffering. In general you want a pad and flow
control strategy. Some streams do well and others not.....
If you use a reliable stream you will depend on the protocol for error recovery.
Reliable data streams may not match your data's data structures and may require
larger buffers than an initial back of envelope computation will indicate.
