messagepack #212
Description
Having a separate header.json, catalog.json and 0 or more blocks might not be the best way to manage messages. Instead, having a single file with the message would be "better".
In that case, we could have a packed-message format. Maybe we shouldn't bother too much with inventing something new, and just use plain tar for this.
During transmission, we still use all the parts separately, but once stored on a server, we could pack it.
We have to figure out if this actually would work with things like scanning files etc
