Did Someone Already Reverse Engineer the Extender Protocol?

There have been several projects to figure out exactly how Extenders work so that maybe a Software Extender (Softsled) could be developed outside of Microsoft.  There is a project on CodePlex, though slow moving it seems like people are starting to get an understanding on how things work.  There have been a dozen threads on The Green Button talking about the same, and of course there is a full website dedicated to SoftSled.  No one thus far has come up with anything ground breaking however.

But wait, last night I was browsing SourceForge and found a project started last year called Tufour.  I've never seen anyone link or talk about Tufour, but it says it “Emulates the media center server protocol used by Windows XP Media Center Edition 2005 to allow media center extenders (with a focus on the Xbox 360) to operate as thin clients.”  I know enough about programming to write Hello World, and that's about it.  Anyone want to compile this and see what it really does, if anything (especially in Vista)?

The code is in SVN at SourceForge, who wants to take a stab at it?

Looks like just the opposite of what we would need for SoftSled (server for XBox 360, not a client that would emulate XBox 360).  Plus, it doesn't look like they got very far, still playing with the authentication bits.  There may be some additional info here for the folks at SoftSled.net, however, working on the authentication methods.  But I don't think there is much here.

Microsoft doesn't want us to have SoftSled, so even if someone could get something working, I am sure MS would send out a patch to break it.

If it is a server for such an Extender session, that would be a key piece for understanding the protocol to create a client.

I agree that the chance of truly creating a software Extender is pretty slim, but as long as those smarter than me are working to try I might as well keep the dream alive.

I don't care about a software extender. Just allow media centers to share recorded tv and support a tuner farm and you are set. They could do this today with little effort. I don't understadn why they don't.
