[PD] gui toolkits

[Brian Fay]

One thing I really like about a web technology-based interface is the idea
that maybe the computer running Pd and the computer accessing the interface
wouldn't necessarily have to be the same computer.

I'm imagining running Pd on a small single-board computer, and
patching/interacting with it on a tablet or a phone or a laptop, connecting
over an ad-hoc wireless network.

Node-webkit from my understanding is really only intended to run locally,
as if it were a native application. It includes an implementation of a web
browser so that it can run, and that is where the ~100MB bloat comes from.

Maybe instead of relying on node-webkit we could write our own tiny node
server, and have users jump into their favorite web browsers to access the
interface?

This would lose the convenience of starting Pd like a native program, but
it could be really cool to access it from outside devices.

Does anybody with more knowledge of Pd's internals have thoughts on the
feasibility of this?
