+### Licensed software (Positron, MATLAB, etc)
+
+Some applications proxied this way require a license tied to your institution. 2i2c can mount a license file into user pods as an encrypted secret via KubeSpawner's `extraFiles`, so the license never needs to live in your image. This requires [opening a support request](../../support.md), since it involves handling secrets on the 2i2c side. Securing the license itself with the vendor is the community's responsibility.
+
+:::{note}
+License files mounted into user-servers are visible to the user. The risks associated with this should be considered.
+:::
+
+#### Positron
+
+[Positron](https://positron.posit.co/) is Posit's data science IDE. It's licensed under the [Elastic License 2.0](https://positron.posit.co/licensing.html), which doesn't permit hosting it as a service to third parties except under Posit's **Education Exception**: access restricted to enrolled students or course participants, with any fees tied to instruction rather than software access.
+
+There are two ways to run it on a 2i2c hub:
+
+- **License file inside the Linux Desktop**: mount your institution's Positron license as an `extraFiles` secret, and run Positron as an app inside the [Linux Desktop interface](#interfaces:desktop).
+- **`jupyter-positron-server`**: a `jupyter-server-proxy` extension that Posit maintains specifically for this use case. It enforces the Education Exception itself, issuing signed, per-session licenses via a hub-side verifier service instead of a static file. See the [Jupyter blog post announcing it](https://blog.jupyter.org/positron-server-available-for-academic-use-via-jupyterhub-ae4e406f9444) and [Berkeley DataHub's docs](https://docs.datahub.berkeley.edu/tasks/positron.html) for a working example.
+
+Either way, **confirm with Posit** that your license covers your planned deployment.
+
+#### MATLAB
+
+[MATLAB](https://www.mathworks.com/products/matlab.html) uses the same pattern: your institution's MATLAB license is mounted into the pod as an `extraFiles` secret, and MATLAB runs as an app inside the Linux Desktop interface.
