representation of the packet unless it has serious performance
implications or restricts some functionality that we use or need.

In terms of representation, here are two things that might be relevant to us:

- How do you initialize the message buffer? Do you need to
reinitialize at every layer? Do you reinitialize when you use a
different amsender?

- Are pointers to different sections of the buffer preserved across calls?

What else do we care about related to packet representation?
