Never _is_ the best guideline.

Either send as individual units, or pack it manually, or whatnot.

"#pragma pack()" isn't a universal solution, nor does it help with byte
swapping.

It is EASY to serialize objects when you first write disk/network code,
and it is a severe motherf***er to do it later. The bugs are subtle, hard
to find, and viscious.

You have been warned. Do it right the first time.
