Thanks for the feedback to everybody.

In fact, libfabric-provider-dpa currently builds as a shared library and 
installs as /usr/lib/libfabric/libdpa-fi.so

Let's say it is not my goal for the next week, especially since some 
mandatory features are missing (notably event counters). But eventually, 
why not.

I did say LGPL.

Thanks for the licensing feedback everybody. I will rediscuss licensing 
with both my supervisor (prof. Marco Aldinucci, currently in CC) and A3Cube.

In fact, I didn't do anything special to make it build in a restricted 
environment, but I didn't do anything as well to make sure it builds 
everywhere :)

Apart of my not-so-portable build scripts, your major problem is that 
the provider requires DPALIB, which is part of A3Cube driver offering. 
DPALIB and the driver are open source under LGPL (which partly explains 
my license choice), although they don't distribute it publicly.

If you can't wait to get your hands on it, I suggest you contact A3Cube 
directly also to get access to their fabric: 
http://a3cube-inc.com/contact-us.html. Meanwhile, given this strong 
feedback and interest, I will reach them so that they are directly 
involved in this discussion.
