Hi Salva!

loadlibrary() is a significant low-level feature that may take a while
to make it in to Octave.

It looks like Transplant is only using loadlibrary() to load in the
ZeroMQ library for its use within the Matlab process. There's an
existing Octave Forge zeromq package that provides ZeroMQ bindings for
Octave, using oct-file linkage instead of the loadlibrary() mechanism.
https://octave.sourceforge.io/zeromq/index.html

Maybe you could work with Transplant to provide an alternative
Octave-oriented M-code adapter layer that uses the zeromq package
instead of loadlibrary-based access to ZeroMQ? Then it would work with
existing Octave releases, and you wouldn't have to wait for someone to
write loadlibrary() and for it to work its way into a new released
Octave version.

Cheers,
Andrew
