Hei Roar,

Yes, that should only be a matter of calling net_output straight after
pushing the data on the buffer. If you don't do this, the data will be
buffered untill next scheduler poll, or for as long as the fwdtimer for
the interface is set to. This is to allow stacking of multiple messages in
the same packet.

No - you don't have to reserve space. This is only needed if you have to
make sure there is always room for your message in the buffer(like the
signatures in the security plugin). This is a pretty special case and
should not be needed to be used by many.
No, there is no way to push data on all the buffers in a single call. If
you are to copy the data to all interface buffers you must loop trough the
interface list(like before).
