tl;dr: soon it will be possible to compile libpd into a bytecode blob that browsers can understand and run very efficiently, using a toolchain Pd already uses to build.
The result will be a "web native" version of Pd's core that runs in browsers.
(I'm hand waving away a lot of hard work that other people will do to get this working.)
