I could put more information in the header. The 'handle array' could be an
extra field too.

Some concerns:
1) if 'handle array' size is as an extra field, then the fields must be
retrieved and parsed to compute the whole message size.
2) if the 'handle array' is itself embedded in the header fields, the
header content will need to be updated for each receiver when broadcasting.

The second option might not be so bad after all, but my original design
kept the original message (header+body) untouched.

thanks
