-c --client host:port: connect to server on at

server-side algorithm to serve a remote request:

• extract one chunk
• lz4 compress it
• send it over the network (in lz4 if smaller, plain else)

client-side algorithm:

• download one chunk (and send previous result at the same time, if any)
• lz4 decompress it if needed
• work over it
• lz4 compress the result
• send it (in lz4 if smaller, in plain form else)

Each client needs to negotiate:
ESK: 160 bits
EK: 128 bits
ISK: 160 bits
with the server prior to starting some work.
