VLC: The HTTP interface (macros and RPN evaluator)

If they'd invented a smooth and tight DSL for doing video control, I'd be impressed, but this has the feel of someone getting excited about RPN and looking for a way to crowbar it into the product. Something relevant (and really cool!) for VLC to do with a build-in web-server would be one-click serving of a H.264 stream directly in a player (sniffing for a HTML5 video-tag, otherwise serving a flash-player). But no, we get RPN and a syntax that'd make a 1999 ASP developer cringe.
For the record: VLC is amazing, and one of my first installs on pretty much any computer. I routinely stick it on friends' Windows machines, only to hear them rave about it a few weeks later, because they never have to troll around for codecs.
As a product VLC is really good.
What's not to love? It's either a stroke of genius or an amusingly inappropriate implementation of an embedded scripting language.
