    I guess it's what happens, but the code works in Matlab (with loadlibrary, 
calllib, and so on). Is there any way to make zeromq more verbose? Perhaps that 
could help to understand the issue better...

  So I think now that the actual problem may start with those weird sent 
messages, which do not occur in Matlab
  

These are errors in transplant_remote.m when calling the "what" and "message" 
functions. The first exists in Octave but there should be some sort of 
compatibility issue, whereas the function message is not yet implemented in 
Octave. At least I know better what's going on. I'll need to go to that file 
and adapt it for Octave...

Thanks
