Yes, the registration thing is a bit unusual indeed.
For licensing issues, I recommend contacting the Slicot "librarian", Vasile 
Sima (address@hidden). I asked him for permission to use some of their routines 
in my control-oo package and I got a friendly admission. He just asked me to 
include credits to Slicot. Therefore I don't expect any licensing problems 
related to Octave ...
