@JeffCren: I tried it out and it took a few seconds, but the download did start for me. I'd suggest trying it from a few different browsers. If that doesn't work send me an email and I'll send you the zip file.
@Przemek:Did you download the source code for Disentanglement as a zip file? Git usually does line ending conversion for "text" files, so the newlines in the repository will just be "\n" but when you check the code out on a Windows machine it will convert them to "\r\n". If you downloaded the source code as a zip it probably wouldn't have done that conversion.
You could either use something like GitHub for Windows or Git Extensions to download the code, you could change the code to just split based on "\n", or you could change the line endings in the text file (EditPad Pro can do this and Notepad2 and Notepad++ probably can too).
The "OnYourWayHome" demo is from David Kean's Create a Continuous Client Using Portable Class Libraries MSDN article. Click on "Download the Code Sample", then on the downloads tab and you will be able to get the source (in both C# and VB). That source code is based on the Beta of VS 2012 and Windows 8 Consumer Preview. If you want to build and run the Metro style app on VS 2012 RC and Windows 8 Release Preview, you will have to make a few updates to that app. (The phone version should work as is.)
The TwitterSearch demo is from the MvvmCross project. Currently, the portable library support is in the vNext branch, so that's where I took it from. I had to make a few changes to get the Metro style app to work on VS 2012 RC.
