I thought this  might be of interest, written by Craig Ringer on the
Scribus email list
<http://nashi.altmuehlnet.de/mailman/listinfo/scribus>, "Re: [Scribus]
Creating PDF forms whose data can be saved with acrobat reader):"

"It's a bit different in this case, in that PDF *is* an open format, 
it's fully documented, and you can do basically whatever you want with
it.  You can include your own enabling signature, for example. The only
difference is that Adobe's free Reader product (hardly the only PDF
reader in town) chooses not to honour feature enabling signatures from
people who're not authorized by Adobe."

This is taken a little out of context; there are things you can't
do (like reverse engineering signatures to persuade Adobe Reader to
allow filling in forms you create).
