Stephane,

I've just posted -04, which addresses your comments as follows:

Done, since i've seen one additional "+1".

I've decided to not add this. The reason for that is that there *are*
a few implementations of Padding out there, but there's very little
implementation of the actual recommended strategy in there. The link
you quoted would have belonged to the original Padding draft, but then
again,i only set up the website once the RFC was out ;)

Added a note saying it's only relevant when transport is encrypted,
and added a whole paragraph in the introduction to refer to 7858 and
also 8094.

best,
Alex
