How might the GNU Lesser General Public License (LGPL) impact what I create with Vuo?

The Vuo Framework and compiled Vuo compositions use the ZeroMQ networking library. This library is licensed under the LGPL, and its licensing terms explicitly state that the copyright holders permit it to be used in commercial applications without requiring source distribution or a dual license.

Some Vuo nodes use LGPL code:

These nodes (and compositions you create using these nodes) dynamically link to the LGPL code, so anyone is free to swap in a modified version of the LGPL code. If you create a composition using nodes that use LGPL code, you are not obligated to distribute your source code.

The Vuo Framework does not otherwise incorporate LGPL code.
