Not now, but we can make it happen.

Right now, we first send the VMSD "header", and then we sent whatever
data is in it.

We can it make work the way you want.  Not sure if that is the best way,
though.  Sections that can(or can't) be there make just reasoning about
the stream more difficult.

Later, Juan.
