To be clearer, Windows Azure can run any code that can run on Windows. So if you have x86/x64 code that runs in a Win2k8 OS, you're good to go. And most languages can do that, some with Cygwin. The major ones (Java, PHP, Python, Ruby, Erlang, etc) have phenomenal Windows support out of the box.
For this next bit, see my disclaimer below. The blog post mentions windows.net. That is the domain for the Windows Azure storage services (blobs, tables, queues, etc). In specific, the headers mentioned seem consistent with a storage request made to the blob service.
Disclaimer: I used to work on Windows Azure until a few weeks ago on strategic adoption among other things so I have to put this here. This is no comment on whether the OP's blog post is accurate or not, on any Apple-Microsoft relationship, etc.
