I evaluated Squid which was my first option, due to the existing code on the project I integrated the proxy, it wasn't that straightforward to interact with Squid.

I'm still thinking to use several Pies and it's simpler to evolve the custom-made proxy to support that, if you see the Github repo, it's pretty simple.

Last, getting a Scala project to run on the old Pi was a nice experiment worth trying.
