[Scribus] PDF questions: digitally sign + embed vs. outline

[Femke Snelting]

Hello list,

For the last stage of the Mute-to-Scribus project (almost done!), we 
have a few more PDF questions:

1. How to digitally sign a pdf? On the Scribus wiki I find that this 
should be possible in Scribus, but I can not find how to actually do it. 
Am I overlooking something? (using 1.3.3.9).

2. I am aware that there are many good reasons for forcing fonts to 
outline in pdf export, but is there any way to switch this off 
temporarily or on a case-by-case basis? Using the python scripter for 
example? I've read the discussions on the list here, and tested the 
pdftops solution described here: 
http://nashi.altmuehlnet.de/pipermail/scribus/2007-May/024023.html so it 
is not difficult to create machine readable pdf's from Scribus. But as 
we are having to use .ttf fonts (we might change this for the next 
issue, but that is not possible for the upcoming edition), I am stuck 
with only outlines...

Thanks in advance,

best,

Femke
