The new WordPress is Calypso?

Brunet thinks it’s not going to affect free WP users. Maybe.
What would, I think, be a radical move, would be to recreate the PHP model with node.js.
That is, rather like VB.NET embedded VB and JSP embedded Java in HTML templates, to have a simple persistent node server, loading up Javascript embedded within HTML pages. Purists would gag, of course, at violating the separation of concerns, but this would make it MUCH easier for people to port their PHP applications over to a node world.
Perhaps someone like Zend should be leading this. A next-generation, node-based server, which allowed embedded javascript as an alternative to PHP at the back-end.
