Would it make sense to think of excitations of a node as it they were made of particles of spin occupying states just like electrons in atoms?

I don't want to sidetrack your thread. If I tell you a little of how I understand of spin networks it will be enough different from what you asked about that it could be distracting to you. Please, if I say something, don't let it distract from your line of questioning.
=============
In my view what is most important is that spin networks are the eigenvectors of the area and volume operators---and they form a basis for the Hilbert space.
...Therefore intuitively the labeling on each link must have something to do with area. Since any surface's area operator measures the area of that surface by looking at the labels of all the links through which the surface cuts. That's probably enough to say for now.

marcus said:And entropy is an information theoretic concept. It may in fact depend on the observer (as Padma says) and what he is able to know about what is inside the box or beyond his horizon. And the different microstates he can (or cannot) distinguish.
marcus said:Spin networks are about what we can measure and how the world responds to measurements of geometric quantities and relations.
Spin particles are fundamental particles that have an intrinsic angular momentum, called spin, which can take on half-integer or integer values. Spin networks, on the other hand, are mathematical models used to describe the quantum states of spin particles in a certain region of space.
Spin particles are the building blocks of spin networks. The spin of a particle determines its properties and interactions, and spin networks provide a framework for understanding these interactions and how particles behave in a given system.
There is strong experimental evidence for the existence of spin particles, such as the electron, proton, and neutron. Additionally, theoretical models and calculations based on spin networks have been successful in predicting and explaining the behavior of these particles.
The existence of spin particles in spin networks is crucial for our understanding of the fundamental building blocks of the universe. These particles play a key role in the structure and behavior of matter, and studying their interactions through spin networks can provide insight into the underlying laws of nature.
While spin particles are currently the most well-known and studied particles in spin networks, there is still ongoing research and discussion about the possibility of other types of particles existing within this framework. Some theories suggest the existence of exotic particles with different spin values, and further research could reveal new insights about the nature of these particles and their role in the universe.
