clientside browser version of Spiderpig like as a WebExtension

[tantek]

Is there anyway to run Spiderpig in the browser instead of on Node on a server?

E.g. a Spiderpig SPA?

Or perhaps Spiderpig packaged into a WebExtension that could run on Firefox and Chrome at least?

The goal here is to have a 100% clientside version if possible that does not depend on setting up a server, and can hopefully re-use any clientside-auth required by a site.
