Look even more closely! All that's important for you *is* GPL.
What you can compile from the sources is ready to serve you
on the commandline to build a connection with highly efficient
differential compression and cachinng. Better than anything I
have seen before. Free for all to use who agree with the GPL.

On top of the GPL'd libraries, nomachine.com also offer a
commericial, proprietary product. So what? It is dead-cheap,
if you ask me, and worth every penny.
