Unsigned argument

An arbitrary argument object passed to a netlet on initialisation.

Unlike the signed argument, the unsigned argument is not embedded in the netlet descriptor and instead is delivered alongside it as part of the binding protocol which delivers the descriptor. It is passed to the netlet via the init method of the INetlet interface.

Unsigned arguments exist because it is often convenient to generate and send quickly-changing data without having to sign it, which is computationally intensive. Also, while the netlet descriptor will be platform dependent (tied to a specific programming language), the unsigned argument, like the binding protocol, is not. Hence the unsigned argument is assumed to be no more than a stream of bytes.
