Because I want the packet to own the data and to be able to access
it using a natural interface. With your approach I would have to
write gratuitous code like this.

This goes down the slippery slop of someone else owning the memory
and making sure it is not gone while other objects still reference
it. If that's the functionality you want, then why bother with the
buffer class at all? Simply store a pair: const void*, size_t; it
will be just as convenient.
