User-Space Traffic Shaping

Just stumbled across this: IP Relay, a user-space TCP/IP traffic shaper. The page doesn't load here, but it's available in Debian as iprelay.

Anyone have any information on the IBlogThis and IBlogExtension specifications? I've been googling around for a bit now and I'm having trouble coming up with a solid spec. Does one exist? Do they not work the way I think they do? What I'm looking for is a SOAP or XML-RPC interface for submitting new blog entries (from RSS aggregators in particular). I assumed something this obvious existed, and that the specs above did exactly that, but... yeah. Anyway, if someone can point me at some documentation, I'd appreciate it (yes, I'm thinking about adding support to Raggle).
